VCS B2B Inbound call - Destination Domain Change

[rplantard]

Hello,

I would like to make Inbound Telepresence call on my ExpressWay and CUCM architecture.

The problem is my "Know sip domain" on the internet is sub.domain.com and my CUCM sip domain is domain.com.

I would like to split the "sub" from the destination target for the external inbound call.

On my EXP C:

I try to use transform with regex like (.*)@sub.domain.com to \1domain.com

I try to use my incoming search rule to replace the domain.

Nothing work.

Do i must use CPL for this purpose ? Couldn't we make it differently ?

Call flow :

External company called office@sub.domain.com

The call is redirected on my ExP E global Ip address

my EXP E redirect it on my EXP C

My EXP C should make the domain transform

My EXP C transfer it to my CUCM neighbor with the domain.com domain -> the uri office@domain.com ring.

Thanks

Would be easier to use a transform instead of search rules, search rules only apply for that one particular rule.  When an alias has been transformed it remains changed, and all further call processing is applied to the new alias.

• Pattern type: Regex
• Pattery string: alias@sub.domain.com
• Pattern behavior: Replace
• Replace string: \1@domain.com

I think I already test it.

I will make the test again on the EXP Cand give you back

Thanks

I test it and as you can see we cant see any change in the domain name :/

And when i check the pattern in the maintenance Windows the replace work correctly.

Can you provide a copy of the unmasked transform as well as the search history.

Since this is coming from external organizations, why not put the transform on your Expressway-E, since it's the public facing system?

You can also try the following transform which is simpler than the one that uses regex:

• Pattern type: Suffix
• Pattery string: sub.domain.com
• Pattern behavior: Replace
• Replace string: domain.com

I already try it on my E. Is just seem to be totally ignored. :/

I open a Tac ticket because it does not seem to be normal operation

Can you provide a copy of the search history for one of the failed calls.  Note, by masking the screenshots, we can't see if there is an issue because of what is being covered up.
