Translation rules in Cisco ISR4431/K9

[Mohamed Hussain Siddique]

Dear all

We are in the process of upgrading Cisco voip routers from 38XX  to 44XX routers , we found one of the translation rule which works on 3825 doesn't seems be work with 4431 .

Translation rule  
voice translation-rule 2002
rule 1 /^7\(5490$\)/ /*89392\1/

In 3825 

voip-01#test voice translation-rule 2002 75490
Matched with rule 1
Original number: 75490 Translated number: *893925490
Original number type: none Translated number type: none
Original number plan: none Translated number plan: none

ios - c3845-ipvoicek9-mz.151-4.M10.bin

In 4431 

voip-01#test voice translation-rule 2002 75490
Matched with rule 1
Original number: 75490 Translated number: *89392
Original number type: none Translated number type: none
Original number plan: none Translated number plan: none

ios - isr4400-universalk9.03.16.04b.S.155-3.S4b-ext.SPA.bin

There was no config changes as this is just replacement. 

Please help to check.

Hi Mohamed,

I am not aware of any such limitation or diff behavior of translation rules in ISR 4K compared to other routers, can you configure any other similar translation rule for testing and see if it also faces same issue.

Hi Manish 

For this rule it translates good 

rule 2 /^7\(555[12]$\)/ /*89392\1/

voip-01#test voice translation-rule 2002 75552
Matched with rule 2
Original number: 75552 Translated number: *893925552
Original number type: none Translated number type: none
Original number plan: none Translated number plan: none

but not with 

rule 1 /^7\(5490$\)/ /*89392\1/

Strange ...

Hi Mohamed,

Yes, that's odd, if you have already tried deleting that translation rule, restarting router and re-adding the rule and issue still persists then i will suggest checking this with TAC.

Hi Mohamed,

Can you provide below debugs while testing this scenario:

Basic Debugs

------------

debug dial-peer

debug voip ccapi inout

If you have configured "translation-rule",

   "debug translation"

If you have configured "voice translation-rule", "voice translation-profile",

  "debug voice translation"

Can you please share your solution working with TAC.
