System information
Direct Registration of Polycom RealPresence Systems with CUCM
31
To enable SIP on the Polycom RMX:
1 From the RMX management interface, in the IP Network Services Properties dialog box,
click the IP tab. .
2 Confirm that the IP Network Type dropdown is set to SIP or H.323 & SIP.
3 Click OK.
At this point, the RMX is capable of receiving SIP calls from CUCM, however, care must be
taken to ensure the proper experience for conference attendees. Attending users may dial
directly into a pre-configured Meeting Room conference ID, or alternatively dial into an Entry
Queue which will prompt users to enter a conference ID. One Entry Queue in the system is
designated as the Transit Entry Queue which receives calls with dial strings containing
incomplete or incorrect conference routing information. Furthermore, RMX also allows for
configuration of an Ad Hoc Entry Queue that will allow users to create meetings ‘on the fly’ from
the Entry Queue prompts.
For more information, see the “Meeting Rooms” and “Entry Queues, Ad Hoc Conferences and
SIP Factories“ chapters in the RMX Administrator’s Guide.
Task 2: Configuring RMX to Route Outbound SIP Calls to CUCM (Optional)
If your deployment requires the RMX to out-dial endpoints registered to CUCM, configure the
following steps on the RMX.
To configure RMX to route outbound SIP calls to CUCM:
1 From the RMX management interface, in the IP Network Services Properties dialog box,
click the SIP Servers tab.
2 In the SIP Server field, select Specify.
3 In the SIP Server Type field, select Generic.
4 Select Refresh Registration every 3600 seconds.
5 If not selected by default, change the Transport Type to TCP.
6 In the SIP Servers table, do the following:
a Enter the IP address of the primary call-processing CUCM node in both the Server IP
Address or Name and Server Domain Name fields.
b Ensure the Port field is set to its default value: 5060. CUCM uses this port number by
default.
