Its hard to believe but i am unable to register a cisco 2801 VGW as MGCP, i have deployed numerous MGCP Gws in past but this one has been troubling me for past one week. I tried all the options in the world but cant figure it out.
i have a 2801 gw with 1 ISDN T1 PRI, as soon as i add the gw in CUCM ( 7.0.2) the gw says unregistered while i flap the mgcp in the router ( mgcp/no mgcp) i can see that gw regiters momentarily for maybe 15-20 secs and finally comes back with status as unregisterd. On the GW i can see the isdn d channel is up and is backhauled to CCM ( shows in output of sh isdn status). Also show ccm shows that GW is registered to CUCM.
interstingly when i captured mgcp events debugs from gw and looked at them , the traces tells me that its name issue but i have tried to register the gw with domain name and without domain name and same result.I removed my name server/ domain name commands from gw and assigned a local hostname and used same hostname in the CCM admin page but in both instances the debugs are same ie name issue.
any other ideas...im running latest ios ie 15.0 M and cucm version is 7.0.2.
here are debugs from GW and out put of sh ccm and sh isdn status cmds
