Thread: "loosing" Aastra phone

  1. #1

    Default





    This has happened a couple of times today (currently setting up the box).. when trying to call my Aastra 57i, the caller is directly sent to voicemail.

    When you make a call from the Aastra phone to any extension, you get a busy reply in every case.

    So I went to look at SIP traces, and to my surprise, I found that the INVITE would never be sent to the destination, rather the proxy would block immediately. Here's the message exchange between the Aastra phone and the Quadro. Note that I left out the first invite which is rejected with a 401 response.

    Code:

    As you can see from the trace, the message is never sent to the phone, which confirms the lack of any messages arriving at the phone.. When I reboot the phone, everything is back in order again.

    And here's the trace from the reverse situation - somebody trying to call my Aastra phone. Once again you can see that nothing is sent to the destination..

    As you can see, the PBX doesn't even bother forwarding the INVITE to the destination, it answers it itself.

    Of course I checked the status page, and extension 55 shows up as registered.

    And it's not like everything doesn't work anymore.. I have 3 BLF buttons configured on my Aastra phone - and those still do work. I also rebooted (including a hard reboot with cutting power) the phone multiple times - and the problem remains. I guess I'll reboot the PBX next.



    Another update: multi extension ringing still has the affected phone ringing as does the intercom feature.

    It's hard to say something having only SIP traces. All I can see is that the phone is in Busy state from the Quadro perspective, so the Quadro isn't trying to initiate a call to the phone and activating VMS. Either the phone is reallyin Busy state (phone problem) or the Quadro lose the phone's state. Next timeyou'll have such problem, please download full systemlogs from the Quadro, open a TSS request and attach the logs there for investigation.

    Will do.. all I needed to know is the amount of information you need for such a problem report.

  4. #4

    Default

    The requested information is thecalled and caller parties phonenumbers and phone-types and the systemlogs downloaded right afterthe problem wasreproduced.
