Tranlation Profiles 4digit did to 6digits in failover

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

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

voice-class h323 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]...)

Re: Tranlation Profiles 4digit did to 6digits in failover

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,

Blue

Re: Tranlation Profiles 4digit did to 6digits in failover

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.
