CallManager 4.2 MGCP Partial E1 PRI then H323 in SRST mode!

Question

Hi Guys,
I know MGCP and partial E1's are not supported. I have ISDN 10 channel PRI's running into about 4 sites.
There was a workaround posted on netpro involving changing service parameters to put the last 20 channels out of service.
This seems to work quite well. ccm-manager config server command works fine etc.
I am turning on SRST now, though and the H323 dial peers outbound think my E1 is a 30 channel and want to send calls out channels that dont exist.
Any ideas, or better ways to do this?
Or even better does anyone know when a partial E1 will be supported under MGCP? Our local SE at Cisco says it is not on the road map at all.
Perth is quite small and has lots of partial E1's :)
Cheers,
Tim

Answer 1

There is a lot of changes to be made.
1 - To begin you need to review your voice translation-rules. For example, rule 40 is translating the call into a number you don't have and rule 10 is configured as a set that you're not using.
2 - You need to create a "voice hunt-group" for "111". Please see example below:
voice hunt-group
To create a hunt group for phones in a Cisco Unified Communications Manager Express (Cisco Unified CME) or Cisco Unified Session Initiation Protocol (SIP) Survivable Remote Site Telephony (SRST) system, use the voice hunt-group command in global configuration mode. To delete a hunt group, use the no form of this command.
voice hunt-group hunt-tag {longest-idle | parallel | peer | sequential}
no voice hunt-group hunt-tag
Syntax Description
hunt-tag
Unique sequence number that identifies the hunt group. Range is 1 to 100.
longest-idle
Allows an incoming call to go first to the number that has been idle the longest for the number of hops specified when the hunt group was defined. The longest-idle time is determined from the last time that a phone registered, reregistered, or went on-hook.
parallel
Allows an incoming call to simultaneously ring all the numbers in the hunt group member list.
peer
Allows a round-robin selection of the first extension to ring. Ringing proceeds in a circular manner from left to right. The round-robin selection starts with the number left of the number that answered when the hunt-group was last called.
sequential
Allows an incoming call to ring all the numbers in the left-to-right order in which they were listed when the hunt group was defined.
3 - You configured srst with an ephone-template that doesn't exist!
4 - dial-peer voice 2000 pots is not going to send the "0". Is "0" your site code or is the carrier expecting to see the "0"?
5 - Why does "dial-peer voice 1100 voip" and "dial-peer voice 2000" have the same preference?
6 - voice register pool  1 doesn't have a number assigned...
