Call established but no voice on both ways

Hi everybody,

I'm working on CUCM 9.1.2,  having an issue which is as follows:

I'm trying to make call to an external number  using a SIP trunk to get to the PSTN, the call is established but no voice is heard on both ways.

Any tips, guys?

thanks in advance,

This looks like ip routing

This looks like ip routing issue. You can use the "show sip-ua calls" to see where your media is sent to. You then need to check that the ips listed in there have ip connectivity to each other.

In the show sip-ua calls, you will have two entries for a single call. Once is the UAC ( this is the leg of the CUBE that sends the invite out) and the UAS, the leg of the cube that received the INVITE.
