[cisco-voip] Outbound Video Calls to Webex fail with 481

[Ryan Huff]

This might have to do with DNS. I would review all your internal/external SRV/A records for EXP/CUCM and your DNS zone in EXP.

It sounds like the call is traversing expressway, but call manager may be having trouble finding the call leg via DNS, to connect the codec to.

Pulling CCM traces and debug logs on the codec for a failed call will tell you for sure.

Thanks,

Ryan

Just a single VCSC and VCSE.... single CUCM 11.5... this is just a proof of concept...

Do you have EXP clusters or is this a single C/E pair?
