    Pri Trunking issues

    normrr New Member

      I am having issues with occasional calls that ring the customer station with no audio, with in a second or 2 the same call rings again and audio both ways is fine. The calling party never heard the first answer just a long period of ringback, I also see this in my soft-switch as 20-30 seconds of ringback. I have a SIP Trunk fed 904 2nd Gen onsite that interfaces with a Tadiran Coral IPx 500. This the only site I have seen this at out of the over 60 PRI's I deliver all on 904 platforms. In the logs I see this entry often  2016.02.16 12:09:55 TM.T02 01 IsdnTmStateIdling - clear trunk appearance. Unfortunately I cleared the logs but I have also seen this listed as Unexpected Cleared Trunk Appearance. Has anyone seen this sort of issue before?

              Norman, please reply with the following:

               

              configuration of TA

              Output of "debug isdn l2-f", "debug voice verbose", and "debug sip stack message" running during one of these calls. If the issue is intermittent, you can use this document to start persistent debug logs:

                  Thanks jay, It is a very intermittent issue but I just don't see this on the other PRI's. I will need to set up the debug logging. Here is the config file

                    I am still having issue with about 10 % of calls failing or timing out (408) and the customer tells me that sometimes they get an unassigned when they try to make an out bound call. I know this is trunk related. I can seem to find the messaging error.

                        Norman, in the example you provided, the 900 sends 2 setup messages with no response:

                        We start to tear down the call and we don't receive anything from the provider until about 20 seconds later:

                         

                        06:31:43.442 ISDN.L2_FMT PRI 1  R Sapi:00 C/R:R Tei:00 INFO Ns:81  Nr:67  P:0

                        06:31:43.444 ISDN.L2_FMT PRI 1    M - 02 CALL_PROC  

                         

                        It appears the provider is taking too long to process the call. Thanks

                            Again Jay, Thanks for all the help over the last couple of years. Yes I am getting a delay from the PBX, I have updated the firmware and see 408 coming back. The real question is why on only this PBX do I get intermittent delay and the customer get the occasional unassigned when making an outbound call. I have reconfigured every which way with no change and the Vendor has no tech support from Tadiran. I think its a messaging issue but cant pin it down.

                                Norman, unfortunately there isn't a lot more we can look at from the 900 perspective. We're sending a properly formatted message to the PBX and not receiving a timely response. Even if the PBX didn't like the format of the message, it should reply with some sort of error and not just wait. It even attempts to complete the call, it's just doing it far too late for it to matter. Thanks
