[cisco-voip] Webex Proximity Callback to Video Endpoints with CUCM

[Pawlowski, Adam]

I can’t sign in to this but I would agree, I ended up making a pattern-specific allow rule in the Expressway’s CPL to let this in but it is not great for scaling.

Subject: [cisco-voip] Webex Proximity Callback to Video Endpoints with CUCM

Hey everyone,

With Webex Meetings video callback to a CUCM-registered video endpoint via proximity, Webex always tries the DN at domain.com<mailto:DN at domain.com> format rather than the Primary URI configured.

We've confirmed that the video endpoints advertise the DN at domain.com<mailto:DN at domain.com> as well as the Primary URI but Webex Meetings is setup to prefer DN at domain.com<mailto:DN at domain.com>.

In our organization and many customer organizations, the B2B Expressways do not allow DN at domain.com<mailto:DN at domain.com> calling.

This issue has become much worse with the new Webex join experience launched recently.

At ePlus, my coworker opened a Collaboration Idea for resolving this- https://ciscocollaboration.ideas.aha.io/ideas/COLLAB-I-3255

Webex BU is using this to prioritize fixes and new features.

Can you vote for this issue if it is applicable to yourself or a customer of yours?  We're really hoping to drive some visibility of this issue.

Thanks,
Brian Meade
