Do you see anything shw up on the debugs on the branch router?

Check debug h225 asn1 to see if there is a setup coming from the CUCM. If not, that means the CUCM is not receiving the IP address of the branch gateway from the GK. This could mean a config issue on the GK with respect to the branch gateways, or on the UCM.

Take debug gatekeeper main 10 from the gatekeeper. These debugs will show what's happening on the GK while processing the incoming ARQ from CUCM.

Also please upload the config of the GK, branch gateway here.

Hello Sreekanth,

The problem was in Tech Prefix. I deleted it from Trunk configuration in CUCM, and everything become to work normally. Thanks a lot.
