[Linphone-users] Audio Error

[gregor]

hi,

the next problem i have is about the audio connection(s).
we got a hardware-router (Teledat  630 LAN, identical in construction to ZyXEL 
Prestige 650H/HW) a few days ago, and since then incoming audio data is 
received only when it is an incoming call, if i call myself any number, i 
simply cant' hear anything. output from microphone is send andyway.
the nat funktionality forwards these ports and portranges:
8000-8019
10000
5000-5004
5060
my VoIP (SIP) - provider is sipgate.de

does anybody have a solution or at least an idea?

thx, gregor
