Polycom RMX 1500/2000/4000 Getting Started Guide
H-14
The definition procedure is the same as for setting the RMX as trusted
and define Static routes in the OCS. For details, see "Setting the
Trusted Host for RMX in the Office Communications Server" on page 9.
Make sure that when defining the Static Route it is pointing to the OCS pool and
not to the RMX directly.
Configuring the RMX System
The required tasks are detailed in "Configuring the RMX 1500/2000/4000 for
Microsoft Integration" on page H-80.
Dialing to an Entry Queue, Meeting Room or Conference Using
the Matched URI Method
Once the RMX is configured for integration in the OCS environment (for
details, see "Configuring the RMX 1500/2000/4000 for Microsoft Integration"
on page H-80), the preferred dialing mode to the conferencing entities
such as Meeting Rooms, conferences and Entry Queues is direct dial in
using the domain name defined in the OCS Static Routes. This eliminates
the need to register the conferencing entities with the SIP server and to
define a separate user for each conferencing entity in the Active Directory.
