We have a 3845 ISR gateway (12.4T) and UCM 6.0. The gateway is registered via MGCP, but we cannot get the gateway "endpoint" to register. We have a VWIC T1 card, full T1 PRI, no question marks in "endpoint" configuration on UCM. I have followed the mgcp configuration setup found here; http://www.cisco.com/univercd/cc/td/doc/product/software/ios123/123cgcr/vvfax_c/callc_c/ccm_c/intcnf1.htm#wp1027337
any suggestions on mgcp gateway "endpoint" registration?
