you need some extra dial-peers. if it's a pri you should have pots peer
with a port something like 'port 1/0:23'
then you'll need to make your dial-peer 'destination-pattern' commands a
bit more specific so a call coming in the PRI is definitely routed to
the VOIP dial-peer and off to callmanager, and vise versa. CM may
ignore/reject the call if it does not recognize the source IP address of
the incoming h323 setup from the gateway. use 'h323-gateway voip bind
srcaddr <address>' under one of your interfaces to make sure packets to
CM are sourced from that interface, then make sure CM is configured
with that ip address as an h323 gateway.
