[cisco-voip] GW IP Address in CCM

[Jeff Ruttman]

Hi,
 
I have a voice router configured, and in CCM an MGCP GW configured.  I
put the router on the LAN and all is well except CCM can't see the
loopback interface, so the IP address on the CCM GW is the gig interface
that is connecting the router to the network.  Otherwise it appears that
CCM did its MGCP config on the router just fine.  Turns out CCM can't
ping the loopback interface on the router.
 
I have the router connected ad hoc, not even on the specific network
where it WILL be connected once in production.  I assume there is
something about the networking here that is preventing CCM from seeing
the loopback as I'm currently setup.   My questions:
 
When a newly configed CCM GW and voice router first meet, does CCM look
for a loopback by default?  And since it couldn't find one on the voice
router, it chose the gig interface instead?
 
If I were to put the router on the proper network with the final IP
address on the gig interface, and assuming the loopback interface is
indeed now available to CCM, will it then use the loopback IP, or will I
have to do something to make that happen.
 
Loopback interface on router is Up Up.
 
Thanks
jeff
