OXO--Open Touch connection

[mgsox]

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

Isn't it self explanatory?

thanks for the reply
yes it is !but how do i solve it? both pbx have the same codec. so what is the problem?

framing?

the codec is g711 a-law 20ms ( i should have said that before! sorry) the connection was working when oxo was r8. we have upgraded the system few days a go

if you leave default on OXO side what happens?

[mgsox]

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
