[cisco-voip] Fractional PRI with "ccm-manager config"

I believe you can set the service parameter "Change B-Channel
Maintenance Status 1" as defined under Unified Communications Manager
service parameters.  I think you'll also need to check "Enable Status
Poll" on the voice gateway configuration.

I maybe mistaken but I think that you can only use H.323 with fractional
PRI and not MGCP.

"MGCP gateways do not support fractional PRIs, while H.323 does.
If MGCP is statically configured, fractional PRI support can be
accommodated, but is not officially supported. Cisco's recommended MGCP
gateway deployment configuration uses the automated ccm-manager config
and ccm-manager config server commands covered in a previous blog. When
these automated configuration commands are used, CUCM registers all 24
channels of the PRI with the MGCP call agent. If a fractional PRI of
less than 23 channels is desired, the H.323 protocol is recommended."

UC6. I have an MGCP voice gateway with a fractional PRI and it also has
two FXS cards. If i configure the controller as 12 channels but then
enable "ccm-manager config" (which I need for end user to be able to
configure FXS's as needed) it overwrites the 12 channel controller
config and sets it back to a full 23 channel PRI.

Any suggestions?

Thanks,

Joe C.
