direct RTP media flow on SIP phone using CME

Hi everyone,

I have testing setup of CME and everything works fine expect RTP media always goes through my CME router, even if telephones in same network. Is this works for SIP with CME? I know where MTP which only for SCCP phone.

Also I have kind unknown problem for me if I have access-list on my internal interface audio doesn't work on phone.

I've already done some debugging on access-list and see no problem with it, even adding ip address of phone doesn't solve problem. Logging all deny packets don't reveal any blocked RTP packets.

sh run in attachment

In my case the command is found under voice service voip. The command was added on a later software release, on the T train of 12.4 or 15
