[cisco-voip] fxo port is unregistered after reset

[Eric Pedersen]

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.

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.
