[cisco-voip] Problems with 2811 as H.323-Gateway, CCM 4.1

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.
