I have a CCM 4.1 system and am using 6 digit extensions 2digits i assign and 4 digits are sent from the phone carrior. In fail over if the line appearences are 4 digits it works fine but they will not translate to 6. I have tested the patterns and they test fine but when I test a call in fallback they do not operate

can you post your entire config?

Personally, I don't have good luck with the tranlsation profile assigned in the call-manager-fallback. Lets say for example your DID range is 2000-2999
-----------------------------------
call-manager-fallback
no translation-profile incoming SRST-incoming
!
voice-class h323 1
h225 timeout tcp establish value
!
voice service voip
h323
no h225 timeout keepalive
!
dial-peer voice 20003 voip
description 2000-2999 DID Range - SRST
preference 3
destination-pattern 2...
translation-profile incoming SRST-incoming
voice-class h323 1
session target ipv4:10.111.102.1 <*notice ip of router*>
dtmf-relay h245-alphanumeric
codec g711ulaw
fax protocol pass-through g711ulaw
no vad
-----------------------------------
I added that other h.323 stuff cuz its good practice. I would apply the voice-class h323 1 to your other voip dial-peers. The voice services voip commands allow for call preservation when going from CallManager > SRST.
Its a good idea to have your dial-peer configuration "tighter". What I mean by that is instead of using .T or "...." be more explicit. Again, using 2000-2999 you will have 3 dial peers. one for the subscriber, one for the publisher, and one for srst.
------------------------------------
dial-peer voice 20001 voip
description 2000-2999 DID Range - Subscriber
preference 1
destination-pattern 2...
translation-profile incoming SRST-incoming
voice-class h323 1
session target ipv4:10.1.102.13

dial-peer voice 20003 voip

session target ipv4:10.111.102.1
dtmf-relay h245-alphanumeric
codec g711ulaw
fax protocol pass-through g711ulaw
no vad
---------------------------------------
So basically, add those three dial-peers for each DID range you have (unless of course you have 2000-2999 and 3000-3999 for example, you could change your destination pattern to [23]...)

Adignan,
That looks great. I may not understand a couple of things. (my voice experience goes back 6 whole weeks) I am using MGCP arn't the 2 other dial peers for an H323 set up. and also I want to have CCM handle all my translations in software so I can use certain tools in CCM such as Dial Analizer. Putting them on the interface then looses that functionality correct?
Thanks,

Yeah. I should have looked over the config better, hehe. I just saw the other dial-peers pointing to other IP Addresses and assumed h.323 (what are those other voip dial-peers pointing to?)
So disregard the other crud and just paste this in:
call-manager-fallback
no translation-profile incoming SRST-incoming
!
dial-peer voice 20003 voip
description 2000-2999 DID Range - SRST
preference 3
destination-pattern 2...
translation-profile incoming SRST-incoming
voice-class h323 1
session target ipv4:10.111.102.1 <*notice ip of router*>
dtmf-relay h245-alphanumeric
codec g711ulaw
fax protocol pass-through g711ulaw
no vad
that will properly prefix 31 to your incoming calls during SRST.
