Nortel Converged Ofﬁce Fundamentals — Microsoft Ofﬁce Communications Server 2007

NN43001-121 01.03 Standard

Release 5.0 30 April 2008

New in this release

Ofﬁce Communications Server 2007 features

Signaling trafﬁc between Communication Server 1000 and Ofﬁce

Communications Server 2007 is supported by Multimedia Convergence

Manager (MCM) 3.0 . Media trafﬁc is supported through the Mediation

Server.

The following list shows new Ofﬁce Communicator 2007 client features for

Voice over IP (VoIP) mode:

•Conference Call

•Announced (Consulted) Call Transfer

•Call Forward

•Call Redirect (Deﬂect)

•Dual Forking

•DoNotDisturb (DND)

•Federated calls

Other changes

•The Mediation Server is introduced in OCS 2007 as a new component.

For more information about the Mediation Server, see"Mediation Server"

(page 20). Due to the introduction of the Mediation Server, the following

changes occur:

— Transport Layer Security (TLS) and Secure Real-Time Transport

Protocol (SRTP) are not supported.

— OCS 2007 can talk to the Communication Server 1000 over a

Transport Control Protocol (TCP) or Transport Layer Security (TLS)

link. TLS transport is supported between MCM/OCS Proxy and CS

1000/SPS.

— Video support for Session Initiation Protocol (SIP) gateway calls is

not supported. Direct VOIP to VOIP and RCC to RCC calls can use

video. For more information, see "Feature Interactions" (page 68).

NN43001-121 01.03 Standard

Release 5.0 30 April 2008

10 New in this release

— SIP UPDATE method is not supported by Mediation Server. This

method enables SIP Gateways and Endpoints to update the call

information during a call. Because the OCS 2007 Mediation Server

does not support UPDATE, re-INVITE’s need to be sent to the

Mediation Server for every change in the call information during

a call. This has not changed since LCS 2005. There were no

interoperability issues.

— G.711 codec for the short leg (Mediation Server to Communication

Server 1000) and RT audio for the long leg of a call (Mediation

Server to OCS) is supported.

•The Nortel Multimedia Convergence Manager (MCM) 3.0 is introduced in

Converged Ofﬁce. For more information, see "Multimedia Convergence

Manager (MCM)" (page 28).

•OCS 2007 snap-in for MMC. For more information, see "OCS 2007

snap-in" (page 27).

•The 8540 OCS desk phone can register as an OC 2007 client, however,

Microsoft does not support using a CS 1000 twin phone with them.
