The technical requirement of SIP Trunk Service over BSNL internet is as follows:

  2. 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.
  3. 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.
