has anyone been able to get a remote sip client to work. i have a sip client loaded on my iPad and when i am in the office it works great. when i leave the office i change the IP address to my external IP and the client registers and i can make and recieve calls but there is no audio. any help on this would be greatly appreciated.
 
Yep, have it working in a few places, audio issues is always the router/firewall interfering with things, how you fix it depends on the router :)

 
i have a adtran netvanta 3120. did you get it working by forwarding ports?
 
Never used/seen an Adtran, so no help there. But it's normally a SIP ALG/H323 transformation issue or whatever Adtran call their version of that :)

 
Well on most routers we use it needs to be turned off, it's there to help but usually hinders, in answer to your earlier question..yes we use port forwarding :)
