IP2050 No DTMF after call connects, cannot navigate AA at far end, no digits including * & #

Issue is on a SIP Trunk
IP 11XX Sets work fine over SIP Trunk

2050 works on Analog Trunk fine.

I cannot seem to find the difference between the IP Set and the 2050.

Anyone recall this?

RE: IP2050 No DTMF after call connects


Update, getting close!

RFC2833- no such settings on the 2050
Codecs - tried all

I found the 2050 works ok on other SIP accounts I have :
Sipgate and Voip.Ms - works
Call Centric - I seem to have lost Audio on that account so cannot test

I just tried F808 Long Tones and it worked!

I tried several several RFC2833 Payload settings between 97 and 127 on SIP Trunks but no go.
