| Don't get held up on SIP on the NRS to only indicate connectivity to an MCS.
The war of the H.323 and SIP is been fought out in the IETF and other communities. Right now SIP is winning and H.323 will eventually will phase itself out.
You will notice on your keycode sheet 2 types of ports H.323 Access Ports and SIP Access Ports. These are the same as the old Virtual Trunks.
CallPilot on the MCS was pulled last release and I don't think they brought support back for it as of yet (i.e. CP Support on a standalone MCS).
CallPilot in a future release is supposed to move the Channels to IP to get around the trans-coding issues which happen today. This is where you will see SIP and CallPilot come together.
You could on a greenfield installation set up two sites with SIP Access Ports instead of H323 access ports. The Gatekeeper becomes a Redirect/Registrar server, set up is different but at the end of the day you are acomplishing the same thing as you did with H323.
Remember that SIP and H323 are means of setting up and tearing down calls. The transport is still IP. |
