I have the UCedge app on my iPhone and everything is connected and working except i am not getting audio in either direction.

Everything except the most important(voice/audio) part works. Calls connect with no issues. If i transfer the call to another phone the call is there. Any suggestions?

I have reset the MIPU card
I have Changed the "16 IPT NAT/No Peer to Peer" in 250 IPT DATA ASSIGNMENT on emanager.

Thanks in advance

the iPhone doesn't support the G711 Codec. Switched to G729A and it worked.

I have it working on G711 as the primary codec with my IPedge without a problem.
This is the same for iPhone / Samsung Android

So many something else? I have another user now not able to work...

Any thoughts?

something in the router? try enabling or disabling sip-alg

what model router is it?

The UCedge doesn't use SIP as it is an IPT softphone using Megaco

Check the port forwards are done properly as there are a LOT that need to be done for the UCedge app to work correctly.
There are also different ports for Apple App compared to the Android App

There is a good tech bulletin detailing the configuration and ports used for UCedge.
