Well, you are somehow right, but the problem is there are TWO VIA:
fields in the packets!
Here's how it looks with another registrar, don't know what software
they use :( (clients are .3 and .4, server is .1)
SIP/2.0 180 RINGING
Via: SIP/2.0/UDP 10.0.0.3

... and the call goes on OK. But with partysip:
SIP/2.0 180 RINGING
Via: SIP/2.0/UDP 10.0.0.1
Via: SIP/2.0/UDP 10.0.0.3
^^^^^^ this seems to be the problem...
