[Freeswitch-users] Alcatel 4018 - "481 Call Does Not Exist" on re-REGISTER

[Christian Benke]

Hi!

I've setup an Alcatel 4018 in SIP-Mode to register with FreeSWITCH.
The initial registration after startup works fine - the phone sends a
REGISTER -> FreeSWITCH answers with 401 -> UA sends REGISTER including
authorization-data -> 200 OK

But after a while the phone's registration expires, as it sends
subsequent REGISTERs _with_ authorization-data right away, which is
answered by FreeSWITCH with "481 Call Does Not Exist".

I'm not exactly sure if the behaviour of the intitial REGISTER is
required(Send authorization-data after 401 has been received) or if
the proxy should understand a REGISTER including authorization data.
If the latter is true, is there a parameter in FreeSWITCH to allow
this behaviour?

I've attached traces of both communications, the initial successful
registration is "register_alcatel_success.dump", the failed
registration is the trace in "register_alcatel_fail.dump"

Best regards
Christian
