Outside Calling Issue on Cisco MX200G2

[inderpreetsingh23]

Hello Everyone,

I have MX200G2 registered on CUCM. When I dial the other video endpoints registered to CUCM the call works fine. 

Now if I want to dial any user outside my organization i.e I want to dial any Public IP the call does not go through. Can someone please guide me how to do the configuration for the same? 

My CUCM version: 10.5(2)

Screenshot attached for the failed call:

Disconnect cause	Bad Request - 'Malformed/Missing URL'
Disconnect cause code	400 (SIP)
Disconnect cause type	RemoteDisconnect
Occurrence type	NoAnswer

Thanks

Just to be sure, are you trying to dial an IP Address, or SIP URI?  Also, your screenshot didn't get uploaded/attached to your post.

If you want to dial an IP Address, CUCM doesn't support this out of the box, though you can make it possible though using your VCS-Control/Expressway or Expressway-Core/Edge, see the below document.

Hi Patrick,

Yes, I was trying to dial IP address from the CUCM. 

Deploying VCS for Dialing the same, as I also came to know the same that CUCM does not support IP address dialing.

Thanks
