asterisk users - Feb 2005 - Asterisk 1.0.1 - CCM 3.0.3 - GNUGK 2.0.8 - OpenH323

OK - I have an cisco MGCP gateway controlled by a Cisco Call manager.

There is a gatekeeper controlled 323 trunk between callmanager and 
asterisk (we use asterisk for vmail, sip phones, park/pick/meetme, etc..).

We are using GK routed mode in gnugk.  All extensions in h323.conf and 
callmanager register with gatekeeper just fine and can communicate.

Dialing sccp phones from sip through the trunk worked just fine, but 
dialing sip from sccp would not.  I had to add the sip extension in 
h323.conf so it would register with the gatekeeper, and then I could 
successfully call it from sccp..  Is there a better way to accomplish this?

Also, SIP phones from asterisk cannot use the mgcp gateway through call 
manager - the gatekeeper just keeps saying ............ not registered 
as an endpoint.  I have tried setting all of the all unregistered, etc 
settings in gatekeeper.ini to allow traffic to pass through with no luck.

Does anyone know how I can get the gatekeeper or asterisk to pass calls 
through callmanager which will in turn pass it to the mgcp gateway for 
outbound calling?

Thanks,

Greg
