Level 3 Communication Interoperability Issue

I need to work with interoperability between Cisco AS5300XM and Level 3 over VoIP. But need ideas about the Cisco equipment setup. Level 3 said "you need E.164 numbering plan and check the Call-ID" .

About the E.164 insert the symbol "+" plus the 11 digit 1+area code+number

Please let me know any ideas

thanks

Re: Level 3 Communication Interoperability Issue

Hi,

you can use a translation-rule like:

voice translation-profile e164

translate called 100

voice translation-rule 100

rule 1 /^1/ /+1/

dial-peer voice 33 voip

destination-pattern 1[2-9][0-8][0-9][2-9]......

translation-profile outgoing e164

That will add the required + for US domestic calls. Repeat in other DPs as necessary for other destinations.

You may even try without the +, just use 011 for example. Chances are it will work anyway :)

Hope this helps, please rate post if it does!

Re: Level 3 Communication Interoperability Issue

Hi

thanks for your help

I used the following setup and don't work

For Incoming

dial-peer voice 222 pots

destination-pattern +T

port 1/0:D

prefix 1

For Outbound

voice translation-profile e164

translate called 1

translation-rule 1

Rule 1 ^1 +1

dial-peer voice 203 voip

translation-profile outgoing e164

destination-pattern 1.......... (11 digit)

session protocol sipv2

session target ipv4:x.x.x.x:5060 (IP Level3)

session transport udp

dtmf-relay rtp-nte

clid network-number +xxxxxxxxxx (my number)

My equipment is

Cisco AS5350XM

Version 12.4(11)T

thanks

Re: Level 3 Communication Interoperability Issue

Hi,

please configure "voice translation-rule 1" and not "translation-rule 1" as these are different things.

Then when checking, please enable "debug ccsip message" and "term mon", in case of problems you can post the output here.

Note the reason I made an example with a more complicated destination-pattern than just 1 followed by 10 dots, it's because it enforces the NANP and prevents user misdialing. That is always a good thing in telephony.

Also note your DP 222 for inbound seems too relaxed in accepting everything and just sending out.

Re: Level 3 Communication Interoperability Issue

Hi,

We tried several calls to Level 3 equipment , the signaling passed well but not the audio

Another thing if you can help me with understanding this call-id , this is the string that they are requesting us to send to generate call to us ( Level 3 to our equipment)

Example Call-Ids:

DEN05020041014230534123123@209.244.48.214

56393400ad0a02108000000e0c6eab9a@64.24.128.4

I get this for the Cisco box (AS5350XM)

Re: Level 3 Communication Interoperability Issue

Hi,

do you have any FW or NAT between the AS5300 and the internet ?

I can't quite understand the call-id issue, normall the call-id is dynamically generated, for call generated toward you what matters is the called number more than anything else.
