How the Unified CM creates a Space using API for Ad hoc conference hosted by Cisco Meeting Server?

[Meddane]

When an Ad hoc conference is triggered by an endpoint to escalate a point-to-point call into a three-way call.

Hi Meddane,

As far as I know and could see, during all my installations was, that the numbers are random.

Also, I haven't seen any documentation about that yet.

What's the intention behind your question?

Best regards,

I am just wondering how CUCM generates the URI to create a space for ad hoc

Second this. Also when adding more attendees the conference number can be interpreted by some mobile phones as a country code. Is there a way to define this as particular office DDI number for example?

[b.winter]

You mean, when you dial-out from the space, to set the calling number to something else other than the random space number?

[chris.barlow1]

Yes for example the ad hoc conf ID looks like this 004036010048 and a mobile phone may interpret this ID as an incoming call from Canada

[b.winter]

You could manipulate the calling number via translation or route pattern, with calling party mask.

But then you can only set 1 number for all calls made to external from CMS (e.g. your main company number).

Have found this in some Cisco Lab guides for configuring CMS:

"The Unified CM will create a randomly generated meeting number for each adhoc conference"

The only why to influence this is by setting a prefix in the conference bridge settings in CUCM configuration. Then every meeting number starts with this prefix and then uses a random number:

Normally only used, when multiple CUCM cluster use the same CMS.

Conference Bridge Prefix is interesting , thanks @b.winter  for this precious infos
