I don't think it's related to the IP-phone because I notice my
Asterisk-server also gets these messages from my SIP-provider.
The call goes : IPphone --> Asterisk --> SIP-provider
It does not occur always when calling from the same IP-phone. It can be
any IP-phone and phone type. It can also occur at any time : when there
are few calls and when there are many calls.
The negative side when this occurs is that there is no audio when the
calls gets answered. These messages flood the CLI untill the call gets
answered. Then it stops, but there is no-way-audio.
I have a second Asterisk-server (same version : 220.127.116.11) and there I
see that this messages occurs just 1 time in a call.
Could it be an issue of Asterisk ? Timing issue ? Any idea which issue
and how to tune it ?
