appears when your system is trying to register with the SIP server. If the registration fails,
appears. If the registration fails, click Register to retry.
Ports
You can change the SIP UDP signaling port; the default is 5060. You can also enable TCP signaling and
change the TCP signaling port; enter 0 to disable it. You can enable TLS signaling and change the TLS
signaling port only if the SIP Registrar preference is set to Enabled. Choosing Disabled for SIP Registrar
automatically disables TLS signaling. Enter 0 to disable it.
TCP signaling and TLS signaling are mutually exclusive. Enabling one automatically disables the other. If
neither TCP nor TLS signaling is enabled, only UDP signaling is enabled.
NOTE
The system reboots if you change the UDP signaling port, enable or disable
TCP or TLS signaling, or change the TCP or TLS signaling ports.
If you enable TLS signaling, the system attempts to use Secure Real-time Transport Protocol (SRTP) for
media encryption in SIP calls. If the far side supports SRTP, the media is encrypted.
To place SIP TLS encrypted calls you must register to a SIP registrar. Direct SIP TLS calls are not
supported.
Configuring the Virtual Operator
Using the Virtual Operator you can create and connect to conferences.
1. Access Preferences : Virtual Operator.
2. Select the checkbox to enable the operator.
3. Enter a name for the operator which will appear in caller ID and redial lists. (The default is Virtual
Operator.)
4. Select a language.
5. Select Touch Tones or Camera Control as the default navigation method.
6. To create a temporary conference from the Virtual Operator, check Allow users to create
conferences. This allows users interacting with the Virtual Operator to create an on demand
conference that is removed two minutes after the last participant exits the call.
