[cisco-voip] UK PRI MGCP[Scanned]

Thu Dec 3 12:03:02 EST 2009

I have managed to get it to register by reducing the length of my
hostname.

Just got the rest to do now.

Would still like to know the recommendation for partial PRI E1 MGCP

Don't suppose you can show me a copy of that config with the ip's and
passwords removed.

To let you know, I have been using 15 channels on an ISDN30 for over 2
years - in my UK site - with no additional tweaks on CCM or the VGW's

Plus it is supported by TAC - Spoken to Joe a few times I in the past  J

Note: Cisco CallManager does not support the configuration or use of a
fractional PRI when you use it with MGCP. If fractional PRI is
necessary, you can use H.323 instead of MGCP.

This can be found on 
http://www.cisco.com/en/US/tech/tk1077/technologies_tech_note09186a00806
fedbe.shtml#topic1 

It's not supported and won't work without some tweaking.

To do a fractional MGCP T1/E1/PRI you have to configured it as a full
PRI on the gateway.  Then on CUCM check the CallManager service
parameter, Change B-Channel Maintenance Status.

I didn't think you could do MGCP with fractional E1's

thanks
