Inbound call to VoiceGateway Router is not working during SRST

                   Hi guys, I hope you can help me on our problem with our IPT. We cant do inbound call to our voice gateway router during SRST but outboud calls is working. On debug isdn q931 shows that number is unallocated. But debug translation shows the number is being translated correctly. Debug dialpeer shows that no outgoing dial-peer is matched, show dialplan number also shows no match. Attached here is the running config and the debug result. Hope someone can help us.

thanks in advance

Hi aokanlawon,

those are for the analog phones, however the ip phone do have dn assigned to them. See below

Inbound call to VoiceGateway Router is not working during SRST

Hi,

I think the issue is being caused by the number expansion statements in your config.

!
num-exp 1... 817031...
num-exp 2... 817032...
num-exp 3... 817033...
num-exp 4... 817034...
num-exp 5... 817035...
num-exp 6... 817036...
num-exp 7... 817037...
!

The call you have shown in yor Q931 debug shows the called number as:-
Called Party Number i = 0xA1, '2049268500'

The number expansion "num-exp 2... 817032..." will be changing this to:-
817032049

Try negating the number expansion and retest
no num-exp 2... 817032...

Regards,
Alex.

Re: Inbound call to VoiceGateway Router is not working during SR

Hi acampbell,

Sorry its my fault, i attached a wrong config file. That config is for another router on our site. I'll attach the correct one so kindly review it again.

Thanks so much

Re: Inbound call to VoiceGateway Router is not working during SR

Hi aokanlawon,

The attached config file was incorrect. I attached the correct one on my previuos entry. Here is the configuration of the translation rule -

voice translation-rule 1

rule 1 /^2049268500/ /877024000/

rule 2 /^2049268599/ /915135871660/

rule 3 /^20492685/ /8770285/

rule 4 /^20492686/ /8770286/

rule 5 /^20492688/ /8770288/

!

voice translation-rule 2

rule 1 /877024000/ /2049268500/

rule 2 /^8770285/ /20492685/

rule 3 /^8770286/ /20492686/

rule 4 /^8770288/ /20492688/

Im pretty sure its working since on my debug dial-peer, the number is translated to the correct 9 digit number

Inbound call to VoiceGateway Router is not working during SRST

ok I agree that the xlation looks to be working..but i dont see the xlated number on the ccapi debu..Can you try two things

1. rename the xlation profile to something smaller eg srst_in

voice translation-profile srst-10-to-9-digit

translate called 1

2. can you also try remove the number expansion just to test..

lets know the results
