Table 5-8: General Parameters (Protocol Definition)
Parameter Description
SIP Transport Type
[SIPTransportType]
Determines the default transport layer used for outgoing SIP
calls initiated by the gateway.
Valid options include:
[0] UDP (default)
[1] TCP
[2] TLS (SIPS)
Note: It's recommended to use TLS to communicate with a
SIP Proxy and not for direct gateway-gateway
communication.
SIP UDP Local Port
[LocalSIPPort]
Local UDP port used to receive SIP messages.
The valid range is 1 to 65534. The default value is 5060.
SIP TCP Local Port
[TCPLocalSIPPort]
Local TCP port used to receive SIP messages.
The default value is 5060.
SIP TLS Local Port
[TLSLocalSIPPort]
Local TLS port used to receive SIP messages.
The default value is 5061.
Note: The value of TLSLocalSIPPort must be different to the
value of TCPLocalSIPPort.
Enable SIPS
[EnableSIPS]
Enables secured SIP (SIPS) connections over multiple hops.
[0] Disable (default).
[1] Enable.
When SIPTransportType = 2 (TLS) and EnableSIPS is
disabled, TLS is used for the next network hop only. When
SIPTransportType = 2 (TLS) or 1 (TCP) and EnableSIPS is
enabled, TLS is used through the entire connection (over
multiple hops).
Note: If SIPS is enabled and SIPTransportType = UDP, the
connection fails.
Enable TCP Connection Reuse
[EnableTCPConnectionReuse]
Enables the reuse of the same TCP connection for all calls to
the same destination.
Valid options include:
[0] Disable = Use a separate TCP connection for each call
(default)
[1] Enable = Use the same TCP connection for all calls
TCP Timeout
[SIPTCPTimeout]
Defines the Timer B and Timer F (as defined in RFC 3261)
when the SIP Transport Type is TCP.
The valid range is 0 to 40 sec. The default value is SIPT1Rtx
* 64 msec.
SIP Destination Port
[SIPDestinationPort]
SIP destination port for sending initial SIP requests.
The valid range is 1 to 65534. The default port is 5060.
Note: SIP responses are sent to the port specified in the Via
header.
Use “user=phone” in SIP URL
[IsUserPhone]
[0] No = 'user=phone' string isn't used in SIP URI.
[1] Yes = 'user=phone' string is part of the SIP URI
(default).
