Video Call Transfer Office Communicator calls made in Computer mode that have established video can transfer to another Office Communicator user in Computer mode—although the new call is audio only. The transferred Office Communicator user experiences the call becoming audio only. After the transferred call is answered by the new endpoint, video can be established. As with all Call Transfers in Computer mode, it is a Blind Call Transfer, where the call is immediately transferred to the new party.

Local Tones Office Communicator supports the generation of local tones (for example, Ringback), but the tones that the Office Communicator generates are unique tones that are not specific to any country. Ringback is generated only for a configured number of cycles; after which the other end continues to ring, but there is no audible ringback.

Quality of Service Office Communicator does not support Quality of Service (QoS) (L2: 802.1p/q or L3: diffserv).

Voice mail Voice mail is not supported for direct Office Communicator calls. Voice mail is supported only with PCA , SimRing, and CD1 Call Forward No Answer and MCS 5100 Advanced Screening calls.

Long distance/overseas control Long distance or overseas calls from Office Communicator are allowed based on the Network Class of Service (NCOS) for the MARP TN of the number and extension associated with the Office Communicator user. For example, if user david@ocsuser.com has a number and extension of 3052, david@ocsuser.com can call the same long distance and overseas numbers that the number and extension 3052 can on the CS 1000. For more information, see "Configuring the Call Server" (page 151).

MCS 5100 MCS 5100 interoperability and federation with Office Communications Server requires that a CS 1000 reside between the two servers, and is limited to voice.

SIP Trunks TCP or TLS-based SIP trunks are supported. SIP trunks and gateways must be enabled with enough trunks to handle the traffic between the CS 1000 and Office Communications Server. For more information, see "Trunking" (page 55).

Phone mode Office Communicator supports phone mode where it controls the desktop telephone to originate or answer calls and the VoIP mode where voice calls can originate or be answered from the client.

Hold and Transfer Office Communicator supports Hold and Transfer in stand-alone or VoIP mode.
