No it invokes the RSVP call agent on the IOS Router via SCCP message. i.e. use a Software MTP.
On CUCM it's identical to adding an H323 GW.


39. What is a best practice for digit manipulation - in regards to H323 GWs?
You need pots dial-peers for incoming calls and you need a voip dial-peer pointing to the CUCM so the H323 GW and connect the call to those phones.
Push as much digit manipulation to the router as possible - so you can re-use it for SRST.
