Published by Kaz Software. Last reviewed November 11, 2026.

Telecom and contact-centre software is carrier-grade: it has to run all day, handle many simultaneous calls and connect to other networks. Few companies in Bangladesh build it. This guide shortlists five from our Top 25 Software Companies in Bangladesh (2026 Guide) that name telecom, VoIP, helpline or contact-centre work, and explains what to check before you buy.

Editor's note: Kaz Software publishes this guide and lists itself where its work fits. The order follows our Top 25 Software Companies in Bangladesh (2026 Guide) and is editorial judgment, not a scored or audited ranking. Figures marked “self-reported” come from each company's own website and have not been independently verified.

How we chose these five

We started with the 25 companies in our main guide and kept those whose public pages mention telecom, VoIP, helpline or contact-centre work. We did not test any product. Many telecom systems are sold to operators under contracts that are not public, so we rely on what each company and the press have published.

The five companies

REVE Systems

According to its About page, REVE Systems was founded in 2003, is headquartered in Singapore and runs R&D centres in Bangladesh and India. It sells carrier-grade Class 4 and Class 5 softswitches (the switches that route calls between carriers and to subscribers), voice, video and messaging apps, SMS platforms, cloud telephony and an AI-based customer-engagement platform. It reports customers in 82+ countries, more than 5,000 customers, and ISO 27001, ISO 9001 and CMMI Level 3 certification (all self-reported).

Synesis IT

Synesis IT, founded in 2006, builds e-government, health and contact-centre systems. A Daily Star profile lists call-centre solutions among its services and says it has built more than 15 national call centres. Its best-known public project is the national health helpline 16263: The Business Standard reported in October 2020 that the helpline is run by the Health Ministry and overseen by Synesis, and that 10,175,080 people used it between March and October 2020. Synesis also reports a biometric verification monitoring platform for the telecom regulator, BTRC (via Devex).

SELISE Digital Platforms

SELISE was founded in Zurich in 2011 and runs its main engineering hub in Dhaka. A 2016 Daily Star profile lists telecommunications among its focus areas and says it had just signed a Swiss telecom client. It reports ISO 27001 and ISO 9001 certification and 700+ staff across eight locations (self-reported).

Brain Station 23

Brain Station 23, founded in 2006, builds enterprise software for fintech, telecom, pharma and retail clients and reports 900+ staff and ISO 27001 and CMMI Level 3 certification (self-reported). It suits large programmes where the telecom work needs many engineers across several technologies.

Kaz Software

Kaz is not a telecom-equipment vendor, and we say so plainly. Kaz builds custom software and AI, and publishes practical guides on how to choose an AI call center in Bangladesh and how an AI voice call center answers calls in Bangla. It fits teams that already run a call centre and want to add AI to it.

What to ask before you buy telecom or contact-centre software

  • Ask for the uptime target in writing and how failover works if a server or link goes down.

  • Ask for load-test results: how many simultaneous calls the system handled and for how long. Our Top Software Testing and QA Companies in Bangladesh (2026) shows who can run that kind of test.

  • Ask which licences and approvals you need from the regulator, the BTRC, and who applies for them.

  • Ask where call recordings are stored, for how long and who can listen to them.

  • Test it in Bangla. If you plan to use voice menus or voice AI, ask for a live demo with real Bangla speech, not a scripted one.

  • Ask how it connects to your CRM or ticketing tool and who builds the connection.

  • Ask about support hours. A contact centre that runs 24 hours needs support that does too.
