Configuring SIP settings
To configure SIP settings on the MCU, go to Settings > SIP.
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. The MCU can register up
to 50 URIs with the SIP Registrar; these URIs comprise conferences' Numeric IDs and the MCU itself.
If you need to register more than 50 SIP URIs, use prefix based call routing on SIP proxy to route calls
to the MCU, rather than registering individual conferences with the Registrar. Strip the prefix and leave
only conference IDs in the URI before proxy the call to MCU.
