fxo port is unregistered after reset
|
|
| Eric Pedersen 2007-11-23, 1:12 am |
| I'm running Callmanager 5.1(2) and have a 2851 running 12.4(11)T3 with 2
FXO ports. When I reset one of the FXO ports from callmanager it stays
unregistered until I disable and re-enable mgcp on the router. I took a
packet capture, and when I issue the reset I see the callmanager passing
data to the router on the tcp/2428 backhaul connection, which it looks
like the router does not respond too. Sniffer decodes this as a
"MGMT_CHAN_RESET_REQ" message. "debug ccm-manager backhaul packets" on
the router does not show anything.
I thought the tcp backhaul connection was only used for keepalives
between the gateway and callmanager, and for carrying D-channel
information on PRIs so I am surprised to see anything being passed here
when there are only FXO ports on the gateway.
I set up another 2851 with same hardware on our testbench and it stays
registered on reset, and a packet capture shows normal mgcp packets, and
only keepalive traffic (no data) on the backhaul connection as I would
expect.
Has anyone seen anything like this?
Thanks,
Eric

| Do you have 'ccm-manager config' in the router config ?
Is the IOS version on your test setup different then the production router?
If it is same IOS, and hardware, and you have ccm-manager config
perhaps it is a MGCP issue where MGCP starts to get flaky after awhile
and needs to be kicked.

| Putting on "ccm-manager config" on that router fixed the problem, but I
don't have that on the testbench router and haven't had the same
problem. Both of them are the exact same hardware and same IOS.
