  1. Version 2.0 has the same bug!!! It is totally impossible to send\receive faxes via axon!!! In T.38 there is "no_signal" message (in direct connection to SIP server T.38 works fine), and G711 FAX Passthru also could not be used, because AXON responds "408 Request Timeout" to remote host, but not "488 Not Acceptable Here".

     

    COULD SOMEONE INFLUENCE TO SUPPORT IN ORDER TO FIX THIS PROBLEM?

  2. Axon 1.31 + Linksys SPA2102 (5.1.12)

     

    1) Axon sends "408 Request Timeout" to remote host, after receives "488 Not Acceptable Here" from local host.

     

    When remote SIP host detects FAX call, it tryes to reinvite to T.38 protocol, after that AXON sends "Invite" to Linksys SPA-2102 and gets "488 Not Acceptable Here" answer (because T.38 is disabled on Linksys, as it is not correctly supported on all SIP hosts), than it for unknown reason sends "408 Request Timeout" to remote SIP host and session ends. Why it sends "408" but not "488" ???

    2) From time to time I got permanent "491 Request Pending" from AXON to remote SIP host. Allthough I have no active calls to that direction. I've tryed to restart AXON, reconnect - nothing helps. Permament 491.

  3. I have the exact same symptoms after upgrading Axon to the new 1.30 version from 1.09 version. VRS was working flawlessly before the upgrade.

     

    I look forward to hearing a solution from NCH as soon as possible.

     

    Thanks

    -Henry

     

    Any ideas where to find the OLD distribution kit?

  4. Using VRS to record AXON PBX, it correctly detects the calls, starts to record but a) during the call, the graphic bar of the line in VRS is blank (no movement); B) after hanging down, I got file size about 150bytes and 0 seconds long.

     

    Any logs for that problem? Whats the trouble?

     

    P.S. The computer where I using VRS has no sound card, I hope that doesnt matter...?

  5. 2) The error indicates that either extension 101 doesn't exist, or you have not set-up a suitable dialplan to direct calls to the number 101 internally to Axon's extensions rather than to the external line.

     

    It exists and as you can see on the log, it connects to it. Strange behaviour.

  6. Using VRS Recorder for recording digital channels from AXON PBX.

     

    While using it for internal calls, the connection sometimes drops just after one of the callee picks up the phone. If it not drops in first few seconds, I see the graph of VRS Recorder moving, but its level in the red zone, so the recorded file it totally useless, its full of metal crackling sounds, and it is impossible catch any voice from it. Analog recording (from mic. of the sound card - works fine).

     

    When using it for external calls, via the external SIP server, the call never starts to record.

    I hear incoming call, pick up the phone, and got the silence... and verse versa. Without recording feature - everything is working fine.

     

    Using latest versions of AXON PBX and VRS Recorder, both on WinXP SP2. Phones SJPhone and Linksys SPA2102.

    1) Regularly I got message: axon background service crashed because of abnormal exception, it restartes and working fine again. But how to get debug? What is causing it?

     

    2) During internal calls I sometimes got 404 error:

     

    16:13:50 Call 102 -> sip:101@192.168.254.252

    16:13:50 Error returned: 404 Not Found

    16:13:55 Call 102 -> sip:101@192.168.254.252 answered

    16:14:02 Call 102 -> sip:101@192.168.254.252 disconnected

     

    Why? How to get rid of it?
