Not working with the sip-server on AVM FritzBox (registrar)


Some people run a SIP service on their fritzBox (registrar) and want to connect 
from LAN to it.

Connection usually is indicated ok (with STUN-server), but no speech is 
transmitted.

the problem is as descibed here:
"Das liegt jedoch an der FritzBox, welche die falschen (nämlich die privaten) 
IP-Adressen liefert. Andere externe SIP-Gegenstellen sollten die gleichen 
Probleme damit haben." (author of PhonerLite)
.. FritzBox reports wrong addresses - the internal ones

In PhonerLite this problem gets fixed by ignoring this wrong adresses when the 
domain/Realm is fritz.box. OK, this is workaround, but AVM don't want tu 
support connection from WAN anymore.

> What steps will reproduce the problem?
1. enable SIP-service on FritzBox 7170, 7270 or 7390 by installing a client.
2. configure sipdroid with 
name (usually 620 for the first sip client)
Proxy/Registrar: yourdomain_at.dyndns.org
Domain/Realm: fritz.box
Transport: UDP / 5060
3. extended settings: use STUN e.g. stun.sipgate.net:10000

What is the expected output? What do you see instead?
