    Nokia N95 with Avaya SIP (SES) Server

    My Nokia N95 seems to register just fine with our Avaya SES server, and I can make outbound calls properly. The phone shows registered with the server on the server side as well. Unfortunately when I receive an incoming call the phone ends up replying with a "480 Temporarily Not Available".

    Has anybody seen this behavior before? I have setup the phone to register both by IP and by domain name, both with the same effect.

    Re: Nokia N95 with Avaya SIP (SES) Server

    Hi,

    Did u update the firmware ?
    Because, I was able to make and receive calls properly on N95 with the
    new firmware.

    Is the "480 Temporarily Not Available" status after answering the incoming call
    or during the "call ringing" time ? But, if it is even before "call ringing status"
    there may be a problem with your server.
    regards,

    Re: Nokia N95 with Avaya SIP (SES) Server

    I have updated the phone to the latest firmware (v11 series) that the updater will allow.

    I get the INVITE then the phone reply "100 Trying" and
    then the phone replies "480 Temporarily Not Available",
    then the server replies "ACK".

    The phone itself never rings. I am actively using the server
    with several other SIP devices which are working fine.

    I have a tcpdump of the messages if that will help.

    Re: Nokia N95 with Avaya SIP (SES) Server

    The 480 response is due to the
    Accept-Contact: *;+avaya-cm-line=1
    in the request.

    At the moment it's not known if this can be fixed in the VoIP application of the Nseries products, and if yes, when. If it could be possible to remove the header from the Avaya side, it would fix this problem.

    This issue had nothing to do with overwriting the contact.

    Odd that is causing the problem, as it only seems to affect my Nokia devices, which are listed as being compatible with the Avaya SES per Avaya. Do I need to filter the entire Accept-Contact line, or just the avaya-cm portion of the line.

    Just went over the ieft draft on the Accept-Contact rule,
    and it appears the structure of the line:
    Accept-Contact: *;+avaya-cm-line=1

    is valid. Is this just a bug in the N95, or something that would
    affect all Nokia products running the SIP software?
