Enable registering the system to the SIP server by
selecting Yes for each server you are defining.
For redundant SIP deployments, you can enter
information for up to three SIP servers. The XT Series
uses Server 1 as the default SIP server. If Server 1 fails,
the system uses Server 2, and so on.
Server 1 DNS Name
Server 2 DNS Name (Optional)
Server 3 DNS Name (Optional)
Enter the DNS name or IP address of each SIP server,
used to register the endpoint.
Server Model Select the model of the SIP server for the best
interaction. If you are not sure or it is not listed, select
Auto.
3. Configure advanced SIP options as described in Table 28: Configuring SIP-related
parameters on page 125. From the endpoint's main menu, select Advanced to access these
settings. On the web interface, they appear directly below the SIP server settings described
above.
Table 29: Configuring SIP-related parameters
Parameter Description
Transport Outbound Call Select the preferred transport protocol for outbound SIP
calls: TCP or UDP.
UDP/TCP Listening Port Enter the port number used by XT Series for receiving
inbound SIP calls. By default, the system uses port 5060.
Transport Outbound BFCP Select the transport protocol to use when sharing content
via BFCP, from the options listed below. BFCP is a
protocol which coordinates shared videoconference
features in SIP calls, often used by one participant at a
time.
• TCP Preferred: Select to use TCP. If the request fails,
the system tries again using UDP. The request might
fail, for example, if the receiving endpoint only accepts
incoming connections over UDP.
• UDP Preferred: Select to use UDP once. If the request
fails, the system tries again using TCP. The request
might fail, for example, if the receiving endpoint only
accepts incoming connections over TCP.
• TCP Only: Select to only use TCP.
• UDP Only: Select to only use UDP.
