Hi,

 

You can do that using "Media Flow-Through" feature which can be configured on global or dial-peer level. Media Flow-Through is a media path mode where media and signaling packets terminate and originate on CUBE. As CUBE is an active participant of the call, this mode is recommended when connected outside an enterprise (untrusted endpoints).

 

Global Level:

voice service voip

 media flow-through

 

At  Dial-peer level:

Dial-peer voice 10 voip

  media flow-through

 

Have a look on below link.

Muhammad is correct (+5), "media flow-through" will force the media to go through the CUBE as oppose to just serving as SIP Proxy, this is the default and unless someone changed it should work. You can post "show run" for verification. Also, if you issue "show call active voice compact" or "show voip rtp connection" commands while active call is serviced by the CUBE you can analyze if proper media IP addresses are in use to identify if RTP is terminated on the CUBE.
