I am setting up two sites; one is with CUCM, the other with CME. The CME site is able to register to a gatekeeper and so is CUCM. When a phone at the CME site dials an extension at the CUCM site, it works fine. When I place the extensions at the CUCM site in a partition, assign the gk-controlled trunk at the CUCM site a CSS for inbound calls with access to that partition it stops working (I get a message that the call can not be completed as dialed.) It acts as though the gk-controlled trunk does not have access to the extension.
If I just change the extension at the CUCM site by moving it to the default partition, it works fine and can be dialed. I've created new CSS and partitions, same problem. The phones with the CUCM site are assigned the same CSS as the gatekeeper but they seem to work fine when they dial each other. Is there anything I should be looking for on the gk-trunk?
