CTMS error : Call could not be completed because CTMS received a 'SERVICE_UNAVAILABLE' error.

Hi All,

I saw this error on Cisco telepresence Multipoint Switch stating '

Call could not be completed because CTMS received a 'SERVICE_UNAVAILABLE' error.

There was a interop call scheduled via CUVC between two end-points ( 1 VC and 1 CTS):

- CTM is showing meeting scheduled

- OBTP is working fine on CTS

- VC unit was not able to dial the no ( For eg: no generated via CTM to join the call is 1678009) but VC was not able to join the call via this no. Call connected via web-interface though, selecting H323 as protocol....

Could it be an issue with Transforms/ Search plan on VCS or is it related to CTMS itself ??

Any thoughts?

Can someone please confirm whether Interop calls ( Involving CUVC and CTMS ) :

- VC end-points can launch call via SIP/H.323 both or just H323 , and if yes to SIP, what is required to configure as SIP calls are failing but if VC end-point launching the call via H323, its working fine..
