hi all,

 i have a zyxel wifi phone running with SER. it registers fine, and i can dial out. However, i can't hear anything.

configuration is as follows:

 

zyxel behind nat (d-link home router) <->SER on public IP:5060 <->asterisk on same public IP:5070

 

i set up an extension on asterisk to play music, called it from the zyxel. no music.

i am using rtpproxy. and the zyxel is set up with NAT=outbound proxy.

 

if i do the same from an ATA behind the same nat, i get the music.

 

does anyone have a zyxel working behind a nat, and have a config to share? or any other help?

 

all help is much appreciated,

 

yair
