OXO--Open Touch connection

Hi everyone I have a problem concerning the interconnection between OmniPCX Office 9.1 and opentouch 1. They are connected using sip trunk. User A is located in OXO and B in open touch. The algorithm used id G711. When A calls B, the communication is ok. When B calls A the set rings ok when they try to answer the communication is cut (on off hook). On the sip trace I get
SIP/2.0 488 Not Acceptable Here

Isn't it self explanatory?

if you leave default on OXO side what happens?

we have the same issue. that is why we only configured one type of code in both sites to see if there was a mismatch. ( a new codec g722 is on the market!)

Check codec pass-through settings on OXO side.
If you dial from an analog or digital set you have the same issue?

I don't believe it... check the negotiation messages and verify codec is the same. Avoid multicoding

Case solved!
If I configure the ars of oxo to have default compression, it works fine.
It looks like a bug to me but is a work around!
Thank you all for your help
