CME - Sip Trunk (PSTN) Incoming Calls Issues.

Hi everybody,

 

I have the following scenario:

 

IP Phones (7821) - CME --- (SIP Trunk)---- PSTN.

 

The outgoing calls are well, no problems with that. But in the incoming calls in first case (With rel100 enabled) doesnt establish calls.

 

Ok, in SIP-UA I have disabled 180 (disable-early-media 180), then the calls stablish with 3 issues.

 

I don't see Cube sending 200 OK to PSTN.

One way audio (PSTN to Internal no audio).

The calls hangup in 16 seconds.

 

I Tried with Early Offer forced, Rel100 disabled, Xcoding. I can't see the reason that Cube not send the 200 Ok.

 

Please your help, Thank you!
