IOS CUBE Sent SIP signaling to 1 IP and SIP RTP to another IP ?

[Jason Aarons]

I have a new CenturyLink SIP Service.  CenturyLink said it is new and doesn't match the Cisco guides.

In short in CUBE they want me to send calls to their network as;

SIP Signaling IP X.X.156.245:5060

RTP IP X.X.156.244

I'm just drawing a blank on how to setup CUBE to send SIP signaling requests to CenturyLink with different Signaling and RTP destination addresses.  Don't I just send session target ipv4:X.X.156.245:5060 and the SDP takes care of the RTP negotiation part?  Do I really care in my CUBE what their RTP address is?

You should just have to send an invite to the X.X.X.245:5060, the SDP will contain the destination you are expecting the RDP traffic to be sent to. It should be up to them to send the RDP out a specific IP/interface on there end. And no you shouldn't care what the RTP address is. Makes no sense to me.
