Inbound and outbound VoIP connections to the A/V Conferencing Servers in this pool can be encrypted using Secure Real-Time Transport Protocol (SRTP).


Inbound and outbound VoIP connections to the A/V Conferencing Servers in this pool must be encrypted using SRTP. If you require encryption, a participant whose computer is not capable of SRTP encryption will be unable to join any audio/video conferences that are hosted by the A/V Conferencing Servers in this pool.

Note   Office Communicator 2007 clients support SRTP encryption. Legacy clients, such as Office Communicator 2005, support 3DES encryption.


Inbound and outbound VoIP connections to the A/V Conferencing Servers in this pool are not encrypted.
