[cisco-voip] VG224 (sccp)Audio Cutting out after 10 seconds

[Frank Arrasmith]

thanks to all for the suggestions.  I havent got it all the way figured out
yet, but I am onto something.  I did a "debug SCCP events" and saw
something weird.  I saw it attempt a connection to my priority 2 CCM
(which was the one that was registered to actually) and then after a few
more seconds, I saw connection attempts to my priority 1 CCM, and the audio
failed.  I reversed the priority of my CCMs and then it registered and
worked fine.  At this point i though there was something fishy with my
priority 2 ccm. So i removed the known good CCM, and just left the suspect
one.  I was unable to register at all.  I received "registration rejected"
status on gateway config page.  I now have a case open with Cisco TAC to
see why registrations are failing to the suspect CCM.  I think the audio
cutting out was becuase of the switchover and switchback configurations.
It would register to the secondary, and sometime within that 15s interval,
it would try to connect to the primary.  thats the best guess anyway.
Either way, I have working FXS ports now, just using another CCM as
redundant.

sccp ccm group 1

 bind interface loopback0

* associate ccm 1 priority 2(suspect one)
*

* associate ccm 2 priority 1(known good)*

keepalive retries 5

* switchover method immediate*

* switchback method immediate*

* switchback interval 15*
