Notes:

In this article, G.711 voice codec is used and CNG Tone Detection is disabled:

When CNG detection is disabled, the Sonus SBC 1000/2000 theSBC lets the Calling fax machine on either side, ISDN or SIP, to send CNG. However, the Sonus SBC 1000/2000 theSBC is actively listening for and detecting the Fax Answer message that the Answering fax machine sends because Fax pass-thru is enabled.

  • If faxes are failing, check the E1 port counters for slips and frame errors.

  • The frame errors and the slips counters must notbe increasing. You can check if they are increasing by resetting the counters. If the errors are increasing, the issue could be caused by one of the following:
    • System timing / clocking. Check the clock source (System -> System Timing) - it should be set to Network/T1/E1 port and not System/Free run. If the clock source is set to Network, but the Current Active Clock shows as Free run, click Apply and ensure that Current Active Clock is now set to Primary. This should resolve the clocking issue as long as the error counters do not increase.
    • If the Tenor is not configured to register with the Sonus SBC 1000/2000 theSBC local SIP registrar and the SIP Signaling group in Sonus SBC 1000/2000 inSBC constantly goes down, check the contents of the var_config.cfg file (from Tenor Config Manager -> Tools -> Var_config -> Edit) and delete the line specifying the transport protocol as in P108 it is obsolete.
    • Bad E1 cable. Replace the cable.
    • Faulty RJ45 jacks. Replace the cable or fix the Rj45 jacks.
    • Faulty RJ45 socket. Try configuring a different T1/E1 port. Visually check the pins in the E1/T1 ports for any differences.
