SIP Trunk Service
Overview
The paradigm shift in the Telecom arena from Circuit Switching to Packet Switching has enabled SIP Trunk service as an analogue to erstwhile ISDN PRI. Prevailing development of end to end IP blended Enterprise Solutions have paved the way for success of SIP Trunk resulting in generation of huge market demand. Ease of deployment, capacity scaling, maintenance and integration with the customers’ existing IT infrastructure with minimal CAPEX and OPEX is added boon. BSNL being leading Telecom Service Provide has pitched SIP Trunk service as a Next Generation Enterprise Business Trunking Solution to meet Enterprise requirement of high volume, high call rate, voice communication over secured MPLS VPN network. SIP Trunk target niche are Call Centres, Telemarketers, Out Bound Dialling Service Operators, Software as a Service providers, Institutions, Government Organisation, Banking, Customer Support Centres etc.

The technical requirement of SIP Trunk Service over BSNL internet is as follows:
- SIP Trunk will be given on FTTH with Static IPv4 address. The customer can either opt for a new FTTH connection of suitable existing plan with static IPv4 address or upgrade existing FTTH connection of suitable plan with static IPv4 address.
- Suitable plan of FTTH will be decided based on the fallback bandwidth (FUP) for that plan. The fallback bandwidth (FUP) should be more than double the bandwidth required for SIP Trunk. This will ensure that the required bandwidth for toll quality SIP Trunk service (number of concurrent channels x 150 kbps) is always readily available even when internet services are used by the customer simultaneously with SIP Trunk over the same FTTH internet pipe.
- Bandwidth required under FUP should be : 2 x number of concurrent channels x 150 kbps. This should be taken at the minimum available bandwidth after considering.
- Concurrent channels shall be given in increments of 5 starting from 10 to 45.
- Above charges proposed for SIP Trunk is exclusive of FTTH or ILL Plan opted by customer.
