Buying an EPABX for a government tender is different from buying one for a private office. The tender document decides what can be offered, and a bid can be rejected for a missing certificate or an interface that does not match. Most departments and PSUs now ask for an IP PBX rather than an old analog EPABX, but the tender may still use the word EPABX or PABX. This guide lists what IP PBX tender specifications usually cover, and how to check a bid against them.
Start with the TEC certificate
An IP PBX is notified telecom equipment under the Mandatory Testing and Certification of Telecom Equipment (MTCTE) scheme of the Department of Telecommunications. It must carry a TEC certificate to be sold and used in India, and government and PSU tenders ask for the certificate of the exact model offered. Check that the model and software named on the certificate match the bid. Read TEC certified IP PBX and MTCTE for how the scheme works.
Voxdial IP PBX by BitVoice is TEC certified under MTCTE, and BitVoice shares the certificate with every quotation. BitVoice BVS1000 analog gateways, used to connect existing analog phones, are TEC certified too.
A tender checklist
| Tender requirement | What to check in the bid |
|---|---|
| TEC certificate | Certificate for the offered IP PBX model, valid on the bid date |
| On-premise installation | System runs on the department’s own servers, not only in a public cloud |
| Line interfaces | SIP trunks, PRI E1 and analog lines as listed in the tender |
| Existing phones | Analog phones reused through FXS gateway ports |
| Operator console | Central switchboard with waiting calls, extension status and directory |
| Call recording | Recording per route or extension, with access control |
| Call restrictions | Class of service per extension, and call detail records |
| Backups | Scheduled backups to a location the department chooses |
| Security | Encrypted signalling and media, admin permissions |
| Support | Response times, on-site support and training |
Interfaces and existing infrastructure
Most offices already have PRI lines, analog lines and hundreds of analog phones. A tender usually expects these to be reused. Voxdial IP PBX supports SIP trunks from Indian carriers such as BSNL, Airtel, Jio and Tata, PRI E1 lines through cards, and analog lines and phones through gateways. Analog phones keep their existing cable. See PRI to SIP trunk migration and analog phones on an IP PBX.
The operator console
Government offices still rely on a switchboard. The tender will usually ask for an operator position that can see waiting calls, transfer and park them, and find officers quickly. The Voxdial operator console shows waiting and missed calls, extension status through a busy lamp field, directory search and call history, with keyboard shortcuts. Read PBX operator consoles.
Recording, restrictions and records
Ask how recording is switched on and who can listen. On Voxdial, recording is set per incoming route, outbound route, ring group or queue, and only users with recording access can play or download calls. Class of service rules decide which extensions can dial local, national, mobile or international numbers, and call detail records show every call by extension and date. See call restrictions and call accounting and CDR reports.
Security and data
Departments want calls, recordings and reports to stay in house. Voxdial runs in your office or data centre, supports TLS and SRTP for encrypted signalling and media, and keeps an activity log of admin changes. Backups can go to local storage or a server you choose. BitVoice Solutions is ISO 27001 certified as a company. Read PBX security and toll fraud.
Resilience
Check what happens when a line or a site fails. Voxdial can fail over between trunks in the order you set, and branch offices can run their own PBX linked to head office so they keep working if the link drops. Put the PBX, switches and gateways on a UPS. See multi-branch phone systems.
Support and the bidder
Tenders often ask for a local support commitment and training. BitVoice is an Indian company that builds and supports the Voxdial software with its own engineers, with 24X7 support by phone, email and WhatsApp.
Beyond the switchboard
Many departments also need a public helpline. The same platform runs Voxdial Contact Center, BitVoice AI voice agents that can be self-hosted, and a WhatsApp helpline. Read citizen helpline call centres and see the full government solution.
