To configure SIP settings on the MCU, go to | . |
To allow conference participants with SIP endpoints to connect to the MCU by dialing a directory number rather than an IP address, you must configure a SIP registrar. The settings on this page control the MCU's interaction with the SIP registrar and with SIP endpoints.
A SIP call will select the audio and video codecs to use from the set of those both allowed on the 
page and supported by SIP, unless the call is with an endpoint configured with a Custom codec (refer to
Configuring SIP endpoints for more information).
Refer to this table for assistance configuring the SIP settings. After making any configuration changes, click

Specifies the level of SIP registration for the MCU.
Can be set to:
No registration: The MCU will not register with the SIP registrar. This means that a user with a SIP endpoint can only connect to the MCU by dialing its IP address or hostname
Register MCU only: Enables conference participants to dial in to the auto attendant of the MCU
Allow conference registration: Enables conference participants to dial directly in to conferences. For this to work, you must configure the SIP registrar with conference IDs
