Hello world,
As a friend of mine, who is using a AVM Fritz!Box Fon, will surely switch to Fusion soon, I'm checking how to make it work with VFX.
So I created a VoIP account with invalid login (test/test) just to see, if SIP-communication succeeds, but I always get the following error message to every SIP-packet sent:
"Jan 16 21:57:15 voipd[16650]: message from UDP:58.28.20.150:5060 is illegal (Missing required header field (Via))."
So communication completely fails even before the login data is transmitted due to the missing via header, which seems to be part of RFC 3261.
Any idea how to make this work?
regards,
Inquisitor
