H323 not working after converted from MGCP and Cisco Call Manager

H323 not working after converted from MGCP and Cisco Call Manager

(OP)
We have  a site that has call manager and a 2821 as a voice gateway. The gateway is configured as mgcp. We have four fxo ports and a t1 pri coming into the network. We switched phone providers and attempted to make the change last night, unfortunately we ran into some problems and I hope someone here can help.

We configured the new pri from the CLI. The new pri is a fractional pri so we only set up 15 channels and 1 b channel.  When, we did this, when we attempted to call out, the call would reach the voice gateway but it would drop. At that point, we configured the PRI port as mgcp from the Call manager. Once we did that, our configuration changed from the 1-15 timeslots to 1-24. We soon found out that mgcp does not support fractional T1's.

We then removed mgcp from that port and set up the voice gateway as h323 so we can  configure the PRI that way. But now when we try to make a call out, the call never reaches the voice gateway, we get a message stating our call did not go through. The call manager seems to not be routing the call to the VG.

I created a route group and added a route list that contained the ip address of the h323 port on the voice gateway, but nothing. It seems as if Call Manager is still managing that port.

I need to be able to set up that PRI via h323 and to configure the dial peers. The dial peers will be easy, but right now I need some advice on how to get the call manager to route the call to voice gateway. Any help would be appreciated thanks in advanced.

The issue was that we needed the calling number configured on the rout pattern.
