I need an advice (as detailed as possible and i will rate helpful posts ;))
Im going to migrate our Cisco2811 gateways from H323 to MGCP. The two Gateways have 2 Pri E1 each and are connected to Callmanager4.x (1Pub+1Sub). We have 1Route List with 1Route Group that contain the two Gateways.
Here is what im thinking the Migration Plan should look like:
1- Convert only one H323 Gateway to MGCP, if tests are fine -> Migrate the second Gateway to MGCP
1.1 On the Callmanager add a New MGCP Gateway
1.2 Add the new created MGCP Gateway to the Route Group that contain the two H323 Gateways, with MGCP as highest Priority. [is this ok to do?]
2- On the Gateway:
mgcp
mgcp call-agent X.X.X.X 2427 service-type mgcp version 0.1
mgcp dtmf-relay codec all mode out-of-band
controller e1 0/0/0
pri-group timeslots 1-31 service mgcp
controller e1 0/0/1
pri-group timeslots 1-31 service mgcp
dial-peer voice 1 pots
application MGCPAPP
port 1/0:23
ccm-manager redundant-host 1.2.3.5
ccm-manager mgcp
ccm-manager config server 1.2.3.4
ccm-manager config
ccm-manager switchback graceful
interface Serial0/0/0:15
no ip address
isdn switch-type primary-net5
isdn overlap-receiving T302 3000
isdn incoming-voice voice
isdn sending-complete
no cdp enable
isdn bind-l3 ccm-manager

interface Serial0/0/1:15
no ip address
isdn switch-type primary-net5
isdn overlap-receiving T302 3000
isdn incoming-voice voice
isdn sending-complete
no cdp enable
isdn bind-l3 ccm-manager
3- i need help here: how to create route pattern in CCM to replace the existing H323 dial-peers/translation rule configuration? here is the actual config:
voice translation-rule 1
rule 1 /^\(.*\)/ /0\1/ type subscriber subscriber
rule 2 /^\(.*\)/ /00\1/ type national national
rule 3 /^\(.*\)/ /000\1/ type international international
!
voice translation-rule 4
rule 4 /^4414/ //
dial-peer voice 1 pots
destination-pattern 0.T
progress_ind setup enable 3
progress_ind alert enable 8
progress_ind progress enable 8
progress_ind connect enable 8
direct-inward-dial
port 0/0/0:15
!
!
dial-peer voice 10 voip
destination-pattern ...
modem passthrough nse codec g711ulaw
voice-class codec 1
voice-class h323 1
session target ipv4:X.X.X.X
incoming called-number .
dtmf-relay h245-alphanumeric
fax rate disable
ip qos dscp cs7 media
no vad
!
4- to roll back to H323 if something went wrong: issue the no MGCP command?? really important to me, as i need to rollback to H323 if something goes wrong with the migration.
5- MOH: do i need to change anything about how MOH is configured?

Think I need more information, but let's start here:
1. It seems all 4 of your E1's are one big hunt group, so I'm not sure based on the information I have if maybe your should do all 4? Just don't want you incoming our outgoing calls to get messed up when your 2x E1's are filled on the first gateway and the next call spills over to the second. SHOULD work, but.....
1.2. It's OK in concept, but I'm not sure it's really going to work perfectly. Maybe that's why no one is replying to you. It's just as easy to remove it from the list and put it back in later if you need to revert back.
3. I don't know what your translation rules are doing and where they are applied. Are they incoming or outgoing? Can you post your translation profiles and what dial-peers they are applied on.
What does your dial-plan look like. What country. I'm trying to figure out how to get rid of the "begins with 4414" in your translation-rule 4 for a (what I am assuming) is a variable length dial-plan.
2. What's your port 1/0:23 doing? Looks like a T1 PRI.
4. Safest way is to use your terminal emulation program to save the "sh run" output to a text file. Or tftp the running config somewhere. Let's not confuse the issue with some h.323 commands and some mgcp commands, especially if you have to hurry up and roll back to get everything back up running quickly.
5. Shouldn't.
