3825 Gateway will not register with Call Manager 4.1

Unanswered Question
Mar 11th, 2008

This was working last night, not onsite to troubleshoot but can ILO into server and telnet into 3825.

I am able to ping between the units.

Everything looks normal on CCM, except for the gateways not registering.

Sho ccm on the 3825 show:

Alright, just fixed it.

We have these connected through a 3560 switch on VLAN 100. When I tried to ping the switch, .5 it failed the first 2 times then responded.

Not sure why this would have stopped the gateway from registering if .1 and .2 could still ping each other.
