No audio format found to offer. Cancelling call

I have a Polycom 670 with HD G7.22 and a Telematrix 3300IP phone. Here are the following configs

[3310]
type=friend
context=Guest_Rooms
secret=3310
host=dynamic
dtmfmode=rfc2833
username=Room3310
canreinvite=yes
disallow=all
allow=ulaw

[6700]
type=friend
context=Back_Office
secret=6700
host=dynamic
dtmfmode=rfc2833
username=Room6700
canreinvite=yes
disallow=all
allow=g722
allow=g729
allow=ulaw
progressinband=no

When I call from the Telematrix phone I don’t have any issues, but when I call from the Polycom phone to the Telematrix I get the following error

– Executing [3310@Back_Office:1] Dial(“SIP/6700-08372ee8”, “SIP/3310|10”) in new stack
[Nov 11 10:57:24] WARNING[24820]: chan_sip.c:3024 sip_call: No audio format found to offer. Cancelling call to Room3310
– Couldn’t call 3310

Why doesn’t it skip the 722 codec and move on to the next Codec that I have listed in the sip.conf

P.S.

I did search and I found a couple of posts on here about this, but no real solution.

Check the settings on the phone. See what it is trying to use. It also may not be finding the G722 codec and crapping out.
