Cross talk issue on sip inbound calls from Verizon carrier

Hi,

We currently have an issue with the cross talk.
We use sip trunk from Verizon.
We checked DSP and all seems to be good.
Any help would be much appreciated.

Ok. I think it is because media RTP packet going to same port.
Can You do packet capture? I want to see SIP+RTP from Verizon to SBC
