[cisco-voip] UK PRI MGCP

*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_note09186a00806fedbe.shtml#topic1

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