Call is not routed towards IP Phone end user

Level 1

Dear all,

I have installed a PRI on a voice gateway router. I made the following configurations on a router to route the incoming calls towards IP Phone users.

card type e1 0 0

network-clock-participate wic 0

network-clock-select 1 E1 0/0/0

controller E1 0/0/0

pri-group timeslots 1-31 voice-dsp

interface Serial0/0/0:15

no ip address

encapsulation ppp

isdn switch-type primary-net5

isdn incoming-voice voice

no fair-queue

ip forward-protocol nd

!

ial-peer voice 100 voip

destination-pattern 1...

session target ipv4:192.168.100.2

!

dial-peer voice 20 pots

destination-pattern .T

incoming called-number 1...

port 0/0/0:15

!

If we made a call from PRI local netwrok vendor. Tham call properly towards IP Phone users. But if we made a call other than local network. e.g from mobile or other PSTN network than call doen't route towards a users, depiste of that we only hear a single tone. I also attached the debug file.

I enable followig debugs.

What is the problem? and what is the solution of this problem. If you require further details than I am also ready to share that.

Best Regards,

Ali Raza

Ali Raza.

Here is the problem

Called Party Number i = 0x81, '61010'

Your dial peer is looking to match only the 1010

So lets try adding

!

voice translation-rule 1

!###THIS TRANLATES I/C DIGITS

rule 1 /^[2-9]1/ /1/

Rule 2 /^1/ /1/

!

!

Voice translation-profile INCOME-DDI

translate called 1

!

voice-port 0/0/0:15

translation-profile incoming INCOME-DDI

!

Please try this and retest.

Let us know how it went

Alex

Hi Alex,

I try to do that but it doesn't resolve the problem. I already talked with PRI provider that we are also recieving digit 6 with our Extension numbers. At once they changed the configurations and 6 was not displaying with called number but still problem was not resolved. You can see in my first post. I also attach debug with that. Can you see anything else on debugs that I attach on first post. Also I have CUCM7.1(5) in a cluster.

Best Regards,

Ali Raza

Ali Raza,

I messed up with my original translation

Can you ammend the translation to

!

voice translation-rule 1

!###THIS TRANLATES I/C DIGITS

rule 1 /^[2-9]1/ /1/

Rule 2 /^1/ /1/

!

This should work
