inbound call routing

Can anyone point me to a good document on inbound call routing?

Also, if you have any other thoughts on the scenerio below, would be appreciated.

 

We are adding another number to our circuit and I'm trying to figure out how to get it to route.

 

Today we receive 10 digits from the telco:

dial-peer voice 100 pots
 incoming called-number .
 direct-inward-dial

 

Translate them to 3 or 4 digits

voice translation-rule 1  (bogus numbers used here)
 rule 1 /^1234567\(...\)$/ /\1/
 rule 2 /^2234567\(...\)$/ /\1/
 rule 3 /^3234567\(...\)$/ /\1/
 rule 4 /^4234567\(...\)$/ /\1/
 rule 5 /^5234567\(...\)$/ /\1/
 rule 6 /^6123456\(5...\)$/ /\1/
 rule 7 /^712345\(9...\)$/ /\1/
 rule 8 /^723456\(4...\)$/ /\1/
 rule 9 /^733456\(6...\)$/ /\1/
 rule 10 /^743456\(...\)$/ /\1/
 rule 11 /^753456\(1...\)$/ /\1/

Send them to Call Manager

CUCM then has a translation pattern

21xxx that points to endpoint or

219441 (and others such as)

 

Since the new number had overlapping last 4 digits, I tried adding a translation rule for 6 digits

 rule 12 /^4235\(......\)$/ /\1/

 

adding an additional dial-peer to CUCM

dial-peer voice 11134 voip
 preference 10
 destination-pattern [0-9].....$
 session target ipv4:10.X.25.11
 incoming called-number 9T
 voice-class codec 1  
 voice-class h323 1
 dtmf-relay h245-alphanumeric h245-signal
 ip qos dscp cs3 signaling
 no vad

 

And a translation pattern in CUCM for the last 6 digits

123456

 

However I get Cause i = 0x8081 - Unallocated/unassigned number

Re: inbound call routing

Your translations are stripping down the number to 4 digits. You have VoIP dial-peers that match on 3 or 4 digits and then route to the destination, but where do you have the translation profile applied ?

The 3 and 4 digit translations are not the problem. They route fine. it's when I tried adding the new number with the 6 digit translation. I posted those at the end of my first post.

Re: inbound call routing

It should be because you are overlapping your dial plan. Keep it consistent with 4 digits.
Also, send a log with "debug isdn q931" , "debug voip translation" and "debug voice cc inout" enabled for this failed call.

Re: inbound call routing

I can send those debugs as I was testing with the telco previously.

 

Ok, Guess that is going to be a problem since the 4 digit conflicts with another number. -Thanks
