Hi,
I want to implement/distribute 1 DID (ISDN E1 PRI) between two Callmanager express systems.
Lets suppose I have Direct Inward Dial on Central site CME but I want to utilize/distribute half of the DID numbers/pool on the remote CME over the WAN.
How can I configure/implement this scenario? Any reference document would be of great help.
Thanks a lot.

Hi,
You have to use voice translation rule for incoming calls.
When call comes In, you translate it to 1#xxxx you Apply
Num-exp 1#xxxx xxxx (for local DIDs) And Num-exp 1#xxxx 2#xxxx for remote DIDs And
Dial-peer voice 1 voir
Destination-pattern 2#xxxx
Session target ipv4:x.x.x.x
On the second CME, you have to Apply also Num-exp 2#xxxx xxxx
And ephone-dn 123 dual-Line (octobre-Line) nombre xxxx
Plz rate if its correct.

Hi Muhammad,
this can be very easy or very complex and all depends on how you design your dial plan for internal nnumber
as best practice always keep it simple
lets say your DID range 012345XX ( where XX is 00 to 99 )
lets assume that 500 to 549 to be used for the local GW/CME and 550 to 599 to be used for the remote CME
also assuming that you are using 4 digit internal numbers with the above DID site code + 3 digit DID sit eone wil lbe like
1 site ID + 550 to 549
2 site ID + 551 to 599
so you need translation pattern to match incoming called number from the DID range, keep last 3 digits and to prefix the relevant site ID
example call coming to number 01234505 will be translated to 1505 and go to the local register IP phone
while a call to 01234580 will be translated to 2580 and will be sent over the WAN to CME2 and to the local registered IP phone on the remote CME with number 2580
and to send the cal lover the WAN you need a VOIP dial peer with desination aptteren as 25.. in our example
make sur eyou apply the mentioned translation to the inbound pots dial-peer to make sure the called number being translated at the first stage example for the above translation :
voice translation-rule 10
rule 1 /^\01234\(5[0-4].\)/ /1\1/
rule 1 /^\01234\(5[5-9].\)/ /2\1/
!
voice translation-profile P1
translate called 10
dial-peer voice xx pots
description *** Incomming POTS Dial-Peer ***
translation-profile incoming P1
direct-inward dial
dial-peer voice yy voip
description to remote CME
destination-pattern 25[5-9].

Thanks Driss & Marwan, I will try to implement this and will let you know if any further help would be required.
Marwan, can you plz explain the outbound dialing from remote CME as the DID line will be on Local CME? Thanks
