A cisco telepresence SX80 that is registered on Cisco Unified communications manager is calling a registered H.323 endpoint that is registered to a Cisco VCS control within the same campus. The call is placed using 6MB, however only a 1 MB call is set up. Where can you find two possible causes for this issue?

A.	The Cisco Telepresence SX80, which needs an option key to call over 2 MB, which also enables multisite calls
B.	In the region settings in Cisco unified communications Manager
C.	Bandwidth settings in the SIP trunk profile
D.	Legacy telepresence systems that are registered to the Cisco VCS control and can only do 1 MB towards a Cisco Unified Communications Manager system
E.	A link and pipe configuration on the VCS to Cisco Unified Communications Manager Subzone
F.	In the subzone settings of the registered H.323 endpoint
