Hi Bogdan

The first SIP message is from call that WORKS perfectly: the "c header" has a valid IP that handle the media. Below it, we have the message with wrong "c header": there is an invalid IP. This way, the media isnt sent to the media proxy.

I did this dumps in the SIP PROXY. The only way to correct the situation is rebooting the openser. By the way: I dont change anything in the script to make it works.

Best regards

Bruno Machado
