[cisco-voip] Resource unavailable, unspecified

[Nick]

I have an issue with calls being sent to a 3rd party conference bridge, I
have this attached to an E1 on a voice gateway, I can dial into the
conference bridge fine from the PSTN or internally but I am having issues
dialling globally over a gatekeeper trunk to the cfb, the calls come over
the GK as g729, into the CUCM, then through to the gateway and on the debug
isdn q931 I get the resource unavailable, unspecified message'

Is this going to be a codec issue,  I have tried setting up HW transcoding
resources on the gateway and the assigned to a MRGL and assigned this to the
gateway config in CUCM, but I still can't get this to work.
