Cloud PBX and Hosted Call-Centre Platforms in Bangladesh: When Software Supply Becomes Telecom Service

Cloud PBX Bangladesh: where software ends and telephony begins

Cloud PBX Bangladesh deals usually begin as software sales and end as telecom questions. A vendor installs an IP-PBX, then offers to host it, then to manage it, then to supply the trunks and numbers so the customer has one bill. Each step is commercially natural. Somewhere along that path the vendor stops supplying technology to a licensed operator's subscriber and starts providing a telecommunication service itself, which section 35 of the Telecommunication Act reserves to licence holders.[1]

This guide answers one question: when does a technology vendor cross into a regulated service-provider role? It compares software installation, maintenance, cloud hosting, managed telephone systems and bundled connectivity; examines who controls calls, numbers and customer accounts; and covers shared platforms, equipment approvals, foreign cloud infrastructure and vendor contracts. It ends with a classification checklist that software companies can apply to their own product before they sell it.

Summary: A vendor that sells, installs or hosts PBX and contact-centre software for customers who buy their own lines from licensed operators is a technology supplier. A vendor that controls call routing for many customers, holds the telephone numbers and trunks in its own name, and bills customers for calls is providing a telecom service and needs a licence or a licensed partner. The 2025 licensing policy promises light-touch frameworks for cloud-native and enterprise services, but until BTRC publishes them, the existing licence and equipment rules decide the line.

Key point: The question is not where the software runs but who provides the connection to the telephone network. If the customer contracts with a licensed operator for numbers and trunks, a hosted PBX is software. If the vendor supplies them, the vendor is selling telephony, and the IP telephony rules on tariffs, numbering, subscriber registers and interception apply to whoever holds the licence.[4]

Cloud PBX Bangladesh: why the definition reaches software vendors

Section 35(1) of the Bangladesh Telecommunication Act 2001 prohibits anyone, without a licence, from establishing or operating a telecommunication system in Bangladesh or providing any telecommunication service in or from Bangladesh.[1] The definitions are broad. As originally enacted, a "telecommunication system" is a combination of telecommunication apparatus, including switching systems, whether or not physically connected; and a "telecommunication service" includes transmission of speech, any value-added telecommunication service such as voice mail, internet service, directory information and "a service for installation, or maintenance of telecommunication apparatus".[1]

A cloud PBX is a switching system delivered as software. Read literally, the definitions catch hosting it, adding voicemail to it and even maintaining it. That literal reading has not shaped regulatory practice: the licence and registration categories under the 2022 Licensing Regulation, as reported, include none for PBX software or maintenance.[6] But the breadth of the text is the reason a vendor cannot simply assume that software is outside the Act. The definitions have since been amended; check the consolidated text, summarised in our overview of telecommunications law in Bangladesh.

The private-system exemptions

Section 35(3) removes the licence requirement for a system not connected to another system whose apparatus is all in the same premises and used only by the owner or occupier; for a system operated by a single person or organisation, not connected to another system, where that organisation controls all the apparatus, uses all the traffic and uses no radio apparatus; and for installing terminal apparatus on an operator's network.[1] A company's internal extension network fits the first two. A PBX that connects to the public network usually depends on the operator: the enterprise is the operator's subscriber and the PBX is its equipment.

Where this guide fits

Licence categories are explained in our BTRC licence guide and the 2025 restructuring in our guide to telecom licensing reform in Bangladesh. Selling minutes on another company's licence is covered in our guide to white-label VoIP in Bangladesh. This article is about the vendor's own classification.

Five delivery models compared

Vendors rarely sell just one model. The same contract can include licences, hosting and managed services. Classify each element separately, because the most regulated element sets the risk for the whole deal.

Software installation

The vendor sells or licenses PBX or contact-centre software, installs it on the customer's servers and hands over control. The customer buys numbers and SIP trunks from a licensed operator in its own name. The vendor operates nothing. This is the safest model, and the main regulatory touchpoint is equipment import if the vendor supplies IP phones or gateways.[4]

Maintenance and support

The vendor maintains the customer's system under a support contract, with remote access for updates and fault-fixing. The literal definition of telecom service includes maintenance of telecom apparatus, so the contract should be framed as support of the customer's own system, with the customer remaining the operator's subscriber.[1] Remote administration should not extend to the vendor routing or originating traffic.

Cloud hosting for a single customer

The vendor hosts a dedicated PBX instance for one customer in a data centre or public cloud. The customer still contracts with the licensed operator for trunks and numbers, and the operator's trunk terminates on the customer's hosted instance. Functionally, this is the customer's own system located off-premises. We regard it as technology supply provided the vendor does not hold the operator relationship.

Managed multi-tenant telephone systems

The vendor runs one platform for many customers, allocates extensions and features, controls routing rules and monitors traffic. If each customer still has its own operator contract, the vendor is close to the line. If the vendor aggregates traffic onto trunks it contracts for and sub-allocates numbers to customers, it has crossed it. This is the model in which cloud PBX Bangladesh vendors most often drift into unlicensed telephony.

Bundled connectivity

The vendor sells a single package of software, numbers and call minutes, and bills customers for calls. It is providing a telephone service. IP telephony, including phone-to-phone and PC-to-phone service, is the business of a licensed IP telephony operator, which must have an approved tariff before charging and must keep the subscriber register.[4] The vendor needs its own licence or must restructure so that a licensee is the provider.

Who controls calls, numbers and customer accounts

Three control tests separate technology supply from service provision. They mirror the obligations that IP telephony licences impose on providers, which is why regulators reach for them.

Control of calls

Who decides how calls reach the public network? A PBX applies the customer's routing rules to the customer's trunks. A provider routes many customers' traffic over its own interconnection. IPTSP licensees must route domestic and international calls through the prescribed interconnection points and must not bypass licensed gateways, and BTRC can require them to disclose network routing.[4] A vendor that decides routing across customers is performing that function.

Control of numbers

Numbers are assigned by BTRC to licensed operators and remain the Commission's property; neither the licensee nor its subscribers acquire proprietary rights, and the licensee must justify its use on request.[4] If numbers are in the customer's name with the operator, the vendor is a supplier. If a block sits with the vendor, which sub-allocates it to customers, the vendor looks like the operator's reseller.

Control of customer accounts

The licensee must keep a register of subscribers with name, address, national ID number, business registration number, number or IP address and device identifier, available to BTRC and law enforcement.[4] If the operator's subscriber is the vendor rather than the end customer, the register is wrong, and the vendor is the party the operator actually serves. That is the clearest sign that the vendor is reselling.

Shared platforms and hosted contact centres

Hosted contact-centre platforms have a regulatory history of their own. BTRC's 2013 call centre registration expressly covered hosted call centres (HCC) and hosted call centre service providers (HCCSP), permitted call centres to use other centres' infrastructure only with prior permission, and barred operators from extending services to other call centre operators.[3] The call centre registration category is itself being deregulated under the 2025 policy, on expiry of current terms.[2] Registration questions for contact centres are covered in our guide to the call centre licence in Bangladesh.

The policy's approach to cloud-native services

The 2025 policy tells BTRC to enable emerging services, listing virtual network services, private networks, edge computing and cloud-native network functions or network-as-a-service.[2] BTRC may require full licensing for some, while others, "particularly enterprise-oriented or non-exclusive services", may operate under registration, technical enlistment or light-touch authorisation, with guidelines setting scope and conditions.[2]

Telecom-enabled service enlistment

The policy also creates a Telecom Enabled Service Provider enlistment, covering SMS aggregation and other emerging services, with scope defined by BTRC from time to time.[2] Commentators expect value-added and OTT services to sit there.[8] A multi-tenant cloud PBX Bangladesh platform that does not supply connectivity is a natural candidate for enlistment once the scope is published. Until then, there is no enlistment to apply for.

Equipment approvals for PBX and contact-centre hardware

Software vendors are often also hardware resellers, and hardware brings its own approvals.

VoIP devices

The IP telephony guidelines require importers of VoIP adapters or IP phones to obtain BTRC's prior permission, and a licensee may not sell equipment imported under its licence without written permission.[4] Registered call centres likewise need prior permission to import call centre equipment.[3]

Vendor enlistment and import permits

The Bangladesh Telecommunication Regulation (Licensing) 2022 provides registration certificates for radio equipment importers and for vendor enlistment.[6] A local importer of radio equipment must obtain a Radio Equipment Importer and Vendor Enlistment Certificate, which lists the permitted equipment and is valid for two years, and then a no-objection certificate before each shipment arrives. ISM-band equipment in the 2.5 GHz and 5.7 GHz bands, and 6 GHz equipment, are within that regime.[7] Wi-Fi desk phones, DECT handsets and wireless headsets therefore need checking.

Technical acceptance

Under section 57, where BTRC has specified that apparatus needs a technical acceptance certificate, no one may use, distribute, sell, lease or demonstrate it except in accordance with that certificate.[1] Customs and import steps are discussed in our BTRC licence guide.

Foreign cloud infrastructure

Many cloud PBX and contact-centre platforms run from regions in Singapore, India or Europe. For a software vendor that does not supply connectivity, no BTRC licence condition requires local hosting. The position is different once a licensee is involved.

Licensee obligations that assume local reach

IPTSP licensees must provide lawful interception equipment and monitoring, place an operations console at BTRC's premises with six months of traffic data and call records, and give BTRC remote access for inspection.[4] The 2025 policy requires all licensees to maintain lawful interception capability and to follow BTRC's technical modalities.[2] A licensed operator that relies on a foreign-hosted platform for its voice service must still meet these duties, and will push them onto the vendor by contract.

The policy's preference for local hosting

The policy commits the government to measures that encourage content delivery networks and hyperscalers to host facilities in Bangladesh.[2] That is encouragement, not a mandate. ISPs that offer hosted OTT or video conferencing services also need BTRC's prior approval under their 2020 guidelines.[5]

Personal data

Call records, recordings and customer directories are personal data. Parliament passed the Personal Data Protection Bill in April 2026 among the bills replacing interim-era ordinances.[9] Transfer and processor rules are covered in our data protection compliance guide, and recording and AI transcription in our guide to call recording law in Bangladesh.

Vendor contracts that keep the line clear

A well-drafted contract does not change what a vendor does, but it records the facts that support the right classification and allocates the regulatory consequences.

• Subscriber relationship: state that the customer contracts directly with a named licensed operator for numbers, trunks and call charges, and that the vendor is not a party to that supply.
• No resale: prohibit the vendor from reselling minutes or sub-allocating numbers, and the customer from using the platform to serve third parties.
• Routing controls: confirm that routing rules are configured on the customer's instructions and that the platform cannot bypass the operator's interconnection.
• Lawful requests: set out how lawful requests and operator compliance demands are handled, consistent with the interception framework introduced by the 2025 amending ordinance.[10]
• Equipment: allocate responsibility for import permits and certificates for any hardware supplied.[7]
• Regulatory change: allow renegotiation if BTRC guidelines under the 2025 policy reclassify the service or require enlistment.[2]

General drafting principles are covered in our guide to contract law in Bangladesh.

Classification checklist for software companies

Answer each question for every product and every customer contract. A "yes" to any of the first four means the cloud PBX Bangladesh offering needs a licence, a licensed partner as provider of record, or restructuring.

1. Does the vendor contract with an operator for trunks or numbers that serve more than one customer?
2. Does the vendor allocate telephone numbers to customers from a range held in its own name?
3. Does the vendor bill customers for calls, minutes or numbers, rather than for software and support?
4. Does the vendor decide how traffic from several customers reaches the public network?
5. Does the platform let a customer serve third parties, such as clients of a call centre?
6. Does the vendor import IP phones, gateways or wireless devices?
7. Is the platform hosted outside Bangladesh for a customer that is itself a licensed operator?
8. Does the product include voicemail, recording or conferencing sold as separate telecom features?

Cloud PBX Bangladesh scenarios: three vendors, three answers

The checklist is easier to apply to concrete facts. Each scenario below assumes a vendor with a Bangladeshi operating company.

A contact-centre SaaS platform hosted abroad

A Dhaka software company sells a browser-based contact-centre platform, hosted in a Singapore cloud region, to e-commerce firms and banks. Each customer buys SIP trunks and numbers from a licensed operator in its own name and connects them to its own tenant. The vendor bills a monthly fee per agent seat. On the checklist, the answers to the first four questions are no: the vendor is a technology supplier. Its live issues are personal data transfers, the security terms its banking customers will demand, and whether any customer uses the platform to serve third parties, which would bring that customer's own call centre position into play.[3]

A systems integrator with a shared trunk

An integrator runs one multi-tenant PBX, contracts with a single IP telephony operator for a large trunk and number block, and offers forty small businesses a bundle of extensions, numbers and included minutes for a monthly price. Every one of the first four questions is answered yes. The integrator is providing telephony, the operator's subscriber register shows the integrator rather than the businesses, and the bundle price is not the operator's approved tariff.[4] The fix is structural: either the operator contracts with each business directly, with the integrator as disclosed agent and software supplier, or the integrator obtains its own licence.

A foreign UCaaS provider serving multinational branches

A global unified-communications provider wants to give the Dhaka offices of its multinational customers local numbers on its platform. Numbers can only come from a Bangladeshi licensee, so the provider needs a local licensed partner that remains the provider of record for the Bangladeshi numbers and calls, with the platform integrated as technology.[4] If the partner is a licensed operator, the platform must also support that operator's interception and monitoring duties.[2] Investment structure and foreign ownership questions are covered in our guide to foreign company registration in Bangladesh.

Mistakes to avoid in cloud PBX Bangladesh offerings

• Assuming "cloud" means "unregulated". Hosting location does not change who provides the telephone connection.[1]
• Holding trunks and numbers for customers. Aggregating operator services for many customers is resale in substance.[4]
• Billing per minute. Call charges belong on a licensee's approved tariff.[4]
• Importing handsets informally. IP phones, VoIP adapters and wireless devices need BTRC permissions.[4] [7]
• Waiting for enlistment that does not yet exist. The TESP scope and emerging-service guidelines are still to be published.[2]

What to watch in 2027

Three developments will decide where the line settles. First, BTRC's guidelines for the new licence categories, which the BTRC chairman said in December 2025 were awaiting government approval.[12] Second, the government's decision on the revised licensing policy sent on 24 May 2026, which reshapes the access layer that supplies trunks and numbers.[11] Third, the TESP enlistment scope and any light-touch framework for cloud-native services.[2] Since the 2025 amending ordinance, which Parliament enacted in April 2026, BTRC decides most of these categories without ministry approval.[10] [9]

Vendors that classify their products now, and draft contracts that show the classification, will be able to adapt quickly when the guidelines arrive. TRW's corporate and commercial advisory team and customs and trade compliance practice advise software and platform companies on classification, partner structures and equipment approvals; contact TRW to review your product.

Frequently asked questions

Does selling PBX software in Bangladesh need a BTRC licence?

Not usually, where the customer buys its own numbers and trunks from a licensed operator and the vendor only supplies and supports the software. Equipment imports may still need BTRC permission.[4] [7]

Is an internal company phone system exempt from licensing?

Section 35(3) exempts systems confined to one premises or one organisation that are not connected to another system and, for the organisation exemption, use no radio apparatus.[1]

When does a hosted PBX vendor need a licence?

When it supplies telephone connectivity itself: holding trunks and numbers for customers, routing their traffic to the public network and billing for calls. That is IP telephony reserved to licensees.[4]

Can a cloud PBX vendor allocate Bangladeshi numbers to clients?

Numbers are assigned by BTRC to licensed operators and remain the Commission's property, so a vendor should not sub-allocate numbers from a range held in its own name.[4]

Do IP phones need BTRC approval to import?

Yes. The IPTSP guidelines require importers of VoIP adapters and IP phones to obtain BTRC's prior permission, and wireless devices fall within the radio equipment import regime.[4] [7]

How long is a vendor enlistment certificate valid?

A Radio Equipment Importer and Vendor Enlistment Certificate is reported to be valid for two years, with a separate no-objection certificate needed before each shipment.[7]

Can a Bangladeshi operator's voice platform be hosted abroad?

No telecom rule bans it outright, but licensees must maintain lawful interception, a monitoring console at BTRC and six months of records, which the hosting design must support.[2] [4]

Were hosted call centre platforms regulated before 2025?

Yes. The 2013 call centre registration expressly covered hosted call centres and hosted call centre service providers, and shared infrastructure needed BTRC's prior permission.[3]

Will cloud communications platforms get a light-touch regime?

The 2025 policy allows registration, technical enlistment or light-touch authorisation for enterprise-oriented and cloud-native services, but the implementing guidelines were not published at the time of writing.[2]

Is PBX maintenance a telecom service under the Act?

The original definition of telecommunication service includes installation and maintenance of telecom apparatus, but the reported 2022 licensing categories include no maintenance licence. Frame support contracts around the customer's own system.[1] [6]
