[Freeswitch-users] Double Re-Register problem

[Peter P GMX]

Hello,

I habe the following problem when re-registering to an external SIP
provider during a call which results in immediate call-hangups.
- FS re-registers with nonce
- 2ms later FS re-registers without nonce
- external SIP provider asks for credentials
- FS re-registers with nonce
- External provider hangs up call

I think the external equipment (Huawei) gets his messages into disorder
and then hangs up.

My question is: How can I force FS to only register once (without nonce)?
As said, FS tries to register twice within 2 msecs without receiving an
answer in between. FS is on a public IP, so there are no NAT problems
expected (I can see that until the re-register takes place, media is
passed in both directions).


Best regards
Peter
