Remote Call Control with SIP CTI 73
ipDialog Ethernet Phone Office Communicator clients can work with the
ipDialog Ethernet Phone only if it is tandemed through a CS 1000.
Country or region tone configuration Country or region tone
configuration is not supported by Office Communications Server or Office
Communicator.
Conference Incorrect participants are displayed on the conference
conversation window in the following scenario. For example, User A makes
a call by SIP alias in Office Communicator–Computer mode to User B in
Office Communicator–VoIP mode. User B answers the call and conferences
in User C in Office Communicator–VoIP mode. User C is invited to the
conference by phone number. User C joins the conference. This results
in four participants being displayed in the conversation window instead
of three. This is a Microsoft limitation and can be reproduced when the
CS 1000 system, Mediation Server outbound routing, and static Front End
routes are disabled.
Active Directory configuration A record in the Active Directory must be
created for all CS 1000 phones whether there is an Office Communicator
client associated with it or not. If a CS 1000 phone is not in the Active
Directory, an OC client user will notice the following:
• Cannot add the telephone number to the Office Communicator Contact
List.
• Will receive two toasts when calls are made from these telephones.
DTMF detection In order to handle DTMF detection properly with OCS
2007, all network components must support RFC 2833 which means all
Branch or Main offices need to be running a Release. 5.0 software as
a minimum. Otherwise there will be problems interacting with Interactive
Voice Response (IVR) systems, collect calls, using meet-me conference
bridges, and so on.
Remote Call Control with SIP CTI
The Remote Call Control component works in all configurations that include
a Signaling Server and is supported for IP, digital, and analog telephone
types.
Office Communicator client uses the ECMA TR/87 specification. Figure 24
"Simple network diagram" (page 74) shows a sample customer network
that deploys Active Directory, the OCS 2007 Front End, OCS proxy server
with MCM, and CS 1000.
