Dial Peer Configuration on CUBE - Hide outgoing CLI

[Simon Roberts]

Hello All, We have the below outgoing dial peer configured on our CUBE (ISR4331 - Cisco IOS XE Software, Version 17.06.05) which has in the past forced out a number prefixed with 546914 to our service provider with the CLI hidden.  This has worked up until very recently.  Feedback from the telecom provider is shown below.  I'm looking for advice on the next steps to resolve this issue

thanks, Simon

I have reviewed the call examples provided and identified that the PBX is not sending a PAID header within the initial invite.

The PAID (p-asserted identity) header needs to be geographic number that is on the endpoint in an E164 format ((+44) DDI@IP address as standard)), otherwise it will default to the network CLI. This is OFCOM regulation and as per the SIP service description. Please add this and retest.

You can add a PAI with a SIP profile outbound on your dial peer. For additional information on SIP profiles please look at this document.  Use SIP Profiles on CUBE Enterprise Common Use Cases

Something like:

voice class sip-profiles 100
rule 3 request INVITE sip-header P-Asserted-Identity modify "sip:.*@(.*)" "sip:<any number of your range>@\1"

[Roger Kallberg]

Or this if there is no PAI to modify.

voice class sip-profiles 100
 rule 1 request INVITE sip-header P-Asserted-Identity add "sip:.*@(.*)" "sip:<any number in your range>@\1"

Hi Roger, b.winter - thanks for your steer here, it is very much appreciated. Have been working on this issue on and off since last week with no success. I've added the line to the SIP config  - ("request INVITE sip-header P-Asserted-Identity modify "sip:.*@(.*)" "sip:<11 digit number>@\1"  )  - however, when I place a test call and run Debug ccsip mess & Debug voip ccapi  I don't see any reference to the number I've added in the logs suggesting that the syntax of the line added is not correct.  Cisco article is challenging to understand, do you have any further suggestions on what to look out for here , thanks

Please share your configuration in a text file that you attach to the response. Remove any sensitive information before you post.

[Simon Roberts]

thanks Roger

[Roger Kallberg]

This is just a small piece of your configuration, I asked you to share your complete configuration, not just a small snippet.

[Roger Kallberg]

Can you please share the output of these debugs running simultaneously.

• deb ccsip mess
• deb voip trans
• deb voip ccapi inout

Please collect the output after you do an outbound call and attach it as a text file to you response.

Hello bwinter, Roger,  Apologies for the delay in providing an update.  Roger the debug commands you provided helped identify that my test calls were hitting the wrong dial peer.  I added the change you both suggested and then made some further changes and now calls are been presented as "no caller ID" on external devices .  Thanks both for your steer here
