BT VOIP and Axon PBX software

Discussion in 'UK VOIP' started by David Randles, Mar 1, 2008.

  1. Anyone successfully using Axon PBX with BT VOIP service ? My Axon PBX
    software works very successfully with other VOIP providers, but with
    BT there is a (re-)registration issue which I can't solve. I keep
    getting error messages every 10 minutes or so:

    Registered as sip:
    then 1 minute later...
    Register attempt for sip: failed
    400 Too many contact addresses

    Any advice gratefully received.

    Hi David,

    From the call trace, it looks like that Axon send several "contact"
    header in its REGISTER message.Did you set several contact information
    in Axon?

    You can use WireShark to trace the SIP messages between BT and your

    In another way, I suggest you to try miniSipServer. It is a SIP server/
    pbx for window, and very easy to use.
