[cisco-voip] MGCP Fallback to H323 fails with frac pri and ccm-manager config

[Jason Aarons (US)]

Before resetting gateway 12.4(9)T in CallManager via CCMAdmin

controller t1 0/0/0

pri-group timeslots 1-10,24 service mgcp

!

ccm-manager config

 

 

 

After resetting gateway in CallManager

controller t1 0/0/0

pri-group timeslots 1-24 service mgcp

!

ccm-manager config

 

The Trombone feature in ccm-manager config would replace the 10 channels
with all 23 B Channels causing SRST to attempt to use Channel 23 which
doesn't exist, resolution was to remove "ccm-manager config"

 

Is this a bug in CallManager?

In 12.4(4)XC I had FXS ports randomly shutdown on 2811/VIC2-4FXO, fix
from TAC was to remove ccm config -jason

Ruben,

 

Had similar issues in the past; If you are using the ccm config server
and ccm config commands Tac says that there is a long history of
problems with them. Once the ports are initially configured via CM (and
ccm config server); the ccm config server and ccm config command should
be removed.

Hi,

 

I'm having several problems using this functionality in routers running
MGCP with BRI ports. When the callmanager goes offline, all works fine,
but when the callmanager is up again, the router cannot register with
the Callmanager. I've also noticed that there are a lot of commands that
have 'disappeared' form the config, causing the router to behave in this
way.

 

Does anybody have this config working properly? I have the same
situation in two customers, I don't know if it is an IOS problem or
what: there is no bug related with that for the release I'm using
(Version 12.4(4)T4)

 

Thanks in advance, 

 

Ruben
