Poly P017 Administrator's Guide

Setting Description
Enable SIP Enables the system to make and receive SIP calls.
Registration Status Read-only setting shows if your system is registered to a SIP
server.
SIP Server Configuration Specifies whether to automatically or manually set the SIP
server’s IP address.
If you select Auto, you can’t edit the Transport Protocol,
Registrar Server, and Proxy Server settings. If you select
Specify, you can edit these settings.
Transport Protocol Sets the protocol your system uses for SIP signaling (your SIP
network determines which protocol is required).
• Auto: Enables automatic negotiation of protocols in the
following order: TLS, TCP, and UDP. This is applicable only
when using a proxy server.
For unregistered systems, if you set the Transport Protocol
to Auto, the order is TCP then UDP. TLS is not included.
• TLS: Provides secure SIP signaling. TLS is available only
when you register your system with a SIP server that
supports it. If you set this option, your system ignores
TCP/UDP port 5060. Poly recommends you use the TLS
setting when possible.
• TCP: Provides reliable transport via TCP.
• UDP: Provides best-effort transport via UDP.
Force Connection Reuse Disabled by default (recommended).
When disabled, the system uses an ephemeral source port for
outgoing SIP messages. When enabled, the system uses the
active SIP listening port as the source port (5060 or 5061,
depending on the negotiated SIP transport protocol in use).
You can use this setting to establish correct operation with
remote SIP peer devices, which require that the source port
match the contact port in SIP messages.
BFCP Transport Preference Controls content sharing negotiation behavior. When you use
the Binary Floor Control Protocol (BFCP), a relationship is
established between the floor control server and its clients.
What you set here determines how network traffic flows
between the server and clients.
Note: TCP is typically slightly slower but more reliable than
UDP. Some deployments don’t support it, such as with session
border controllers (SBCs).
• Prefer UDP: (Default) Starts resource sharing using UDP
but falls back to TCP if needed.
• Prefer TCP: Starts resource sharing using TCP but falls back
to UDP if needed.
• UDP Only: Shares resources only using UDP. If UDP is
unavailable, your system can’t share content in a separate
video stream.
• TCP Only: Shares resources only through TCP. If TCP is
unavailable, your system can’t share content in a separate
video stream.
