VOIP dial peer won't strip digits

[Xian Li]

Hi,

I have a voip dial peer won't strip called digits. For example, I want to keep the last 4 digits and strip any digits in front. Lets say the incoming number is 12345678 as a example, and I want the voip dial peer 12 to strip 1234 and only keep 5678. Here is the configuration：

voice translation-rule 1
rule 1 /^.*\(....\)$/ /\1/

voice translation-profile sip-incoming
translate called 1

dial-peer voice 12 voip
translation-profile outgoing sip-incoming
destination-pattern 12345678
session target call-manager-ip
voice-class codec 1

And then I make a test call on 12345678 from outside, I can see the call hits the my CUBE router and voip dial peer 12, but the called number after matching the dial peer becomes empty. Here is the debug voip dialpeer inout:

Oct 23 05:14:44.581: //-1/xxxxxxxxxxxx/DPM/dpMatchPeersCore:
Calling Number=12345678, Called Number=12345678, Peer Info Type=DIALPEER_INFO_SPEECH

Oct 23 05:14:44.581: //-1/xxxxxxxxxxxx/DPM/dpMatchPeersMoreArg:
Result=SUCCESS(0)
List of Matched Outgoing Dial-peer(s):
1: Dial-peer Tag=12
2: Dial-peer Tag=10
Oct 23 05:14:44.581: //-1/xxxxxxxxxxxx/DPM/dpAssociateIncomingPeerCore:
Calling Number=XXXXXXXX, Called Number=, Voice-Interface=0x0,
Timeout=TRUE, Peer Encap Type=ENCAP_VOIP, Peer Search Type=PEER_TYPE_VOICE,
Peer Info Type=DIALPEER_INFO_SPEECH

Any idea why?

Thank you

If you're sending the call to CUCM, why not just set the significant digits to 4?

Hi,
This is the dial peer for matching incoming calls from SIP provider who is sending full 8 digits number to me.
Actually I found that even I removed the "translation-profile outgoing sip-incoming" from the config, the Called Number in the output still showing empty. What could be cause?

Thank you

I think you want the dollar sign inside the brackets, to make it clear the variable is the last four digits.   For example, taken from a working installation ..

rule 100 /.*\(....$\)/ /\1/

Are you aware of the "test voice translation-rule" command?  

[Anthony Holloway]

No, having the dollar sign outside of the grouping is appropriate.

VGW#show run | s voice translation-rule 1
voice translation-rule 1
 rule 1 /^.*\(....\)$/ /\1/
!
VGW#test voice translation-rule 1 6125551212
Matched with rule 1
Original number: 6125551212     Translated number: 1212
Original number type: none      Translated number type: none
Original number plan: none      Translated number plan: none

[Xian Li]

Yeah I have test it by using the test translation command.

I don't even think it is the translation profile problem now since even I removed the "translation-profile outgoing sip-incoming" from the dial peer config, the Called Number in the output still showing empty...

Do a Debug ccsip messages for the flow and check if you are getting the calling number.

Please post "debug voice translation".
