You can use H.323 or SIP dial peers between the CME routers that prefer the PRI for outbound calls. You can also set aside blocks of your DID range on the PRIs for the remote site and use dial peers to forward those calls to the correct CME router.
You will need to use caution to ensure that emergency calls (911) always use a local port.
As stated by Jonathan you accomplish this via dial peers, essentailly you configure the GWs as IP-IP GW and redirect the calls to the main GW via voip dial-peers, in order to enable IP-IP feature you need to allow that by using the following commands:
voice service voip
allow-connections h323 to h323
allow-connections h323 to sip
allow-connections sip to h323
allow-connections sip to sip
I put in both H323 and SIP as I am not sure which one you would prefer, and then you have bi-directional dial peers pointing to and from the main site's GW.
The short answer is that you don't.... That isn't entirely true while at
the same time it kind of is, but for the most part you don't configure
the softkeys. You enable or disable them via TCL. Here is the long
answer. Be sure to read the whole thing or e...
