Configuring Protocols for the Cisco Unified Videoconferencing 5100 MCU
•Configuring H.323 Gatekeeper Protocol Settings
•Configuring SIP Proxy Settings
Configuring H.323 Gatekeeper Protocol Settings
You can configure the protocol settings of an H.323 gatekeeper to set how the MCU and the gatekeeper interact.
Note•Changing gatekeeper settings does not reset the MCU, but might disconnect active calls.
•You do need to reset the MCU to disable support for the H.323 protocol.
Procedure
Step 1 Select Configuration.
Step 2 Select Protocols.
Step 3 Locate the H.323 section.
Step 4 Select H.323 to enable the MCU to operate with the H.323 protocol.
Step 5 Enter the IP address and port number for the gatekeeper.
The default port is 1719.
Step 6 Select Apply.
Configuring SIP Proxy Settings
You can configure settings for SIP registrar profiles which set how the MCU and the registrar interact.
Procedure
Step 1 Select Configuration.
Step 2 Select Protocols.
Step 3 Locate the SIP section.
Step 4 Select SIP to enable MCU communication with the SIP proxy.
Step 5 Enter the SIP domain of the MCU in the Default SIP domain field as defined in the SIP server.
An example of a SIP domain is company.com.
Step 6 Select Locate automatically to instruct the MCU to automatically locate one of the SIP proxy servers that are present in the domain,
or
Select Specify and enter the following:
•An IP address or host name of the SIP proxy, for example proxy.company.com.
•The communication port number of the SIP proxy address. The default port is 5060.
•The transport connection type for sending messages to the SIP proxy according to the type supported by the SIP proxy—UDP or TCP.
This field is mandatory. The default is UDP.
Note The Locate automatically option works only if you have configured a valid IP address at Configuration > Setup > Network > DNS server1 or DNS server2.
Step 7 Select Use registrar to instruct the MCU to register with a SIP registrar and to send service information to the registrar.
Step 8 Enter the following information:
•The IP address or the host name of the SIP registrar in the IP address field.
This field is mandatory.
•The communication port number of the SIP registrar address.
•The transport connection type for sending registration requests to the registrar according to the type supported by the SIP registrar—UDP or TCP.
This field is mandatory. The default is UDP.
Step 9 Select More.
Step 10 Enter the number of the signaling port on which the MCU communicates with the SIP proxy.
The default is 5060.
Step 11 Select Use proxy digest authentication to enable MCU authentication with a SIP proxy server using user name and password.
Authentication is performed as defined in RFC 2617. This field is disabled by default.
Step 12 Enter the MCU user name and password.
The user name and password must match the name and password defined on the SIP proxy server.
Step 13 Select Use registrar digest authentication to enable MCU authentication with a SIP registrar using user name and password.
Authentication is performed as defined in RFC 2617. This field is disabled by default.
Step 14 Select Use `Empty Invite' when sending Invite messages to endpoints to enable the remote endpoint to indicate preferred audio and video channels.
Step 15 Select Using Microsoft OCS to enable the MCU to work with Microsoft Office Communications Server (OCS).
Step 16 Select Apply.
