ini File Field Name
Web Parameter Name
Valid Range and Description
SIPTransportType
[SIP Transport Layer]
Determines the default transport layer used for outgoing SIP calls initiated by
the gateway.
0 = UDP (default).
1 = TCP.
2 = TLS (SIPS).
Note: It is recommended to use TLS to communicate with a SIP Proxy and not
for direct gateway-gateway communication.
TCPLocalSIPPort
[SIP TCP Local Port]
Local TCP port used to receive SIP messages.
The default value is 5060.
SIPDestinationPort
[SIP Destination Port]
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.
EnableTCPConnectionReus
e
[Enable TCP Connection
Reuse]
Enables the reuse of the same TCP connection for all calls to the same
destination.
Valid options include:
0 = Use a separate TCP connection for each call (default)
1 = Use the same TCP connection for all calls
LocalSIPPort
[SIP Local Port]
Local UDP port used to receive SIP messages.
The valid range is 1 to 65534. The default port is 5060.
SIPGatewayName
[Gateway Name]
Use this parameter to assign a name to the gateway (e.g., ‘gateway1.com’).
Ensure that the name you choose is the one that the Proxy is configured with
to identify your media gateway.
Note: If specified, the gateway Name is used as the host part of the SIP URI in
the From header. If not specified, the gateway IP address is used instead
(default).
IsProxyUsed
[Enable Proxy]
0 = Proxy isn’t used, the internal routing table is used instead (default).
1 = Proxy is used.
ProxyIP
[Proxy IP Address]
IP address (and optionally port number) of the primary Proxy server you are
using.
Enter the IP address as FQDN or in dotted format notation (for example
201.10.8.1).
You can also specify the selected port in the format: <IP Address>:<port>.
This parameter is applicable only if you select ‘Yes’ in the ‘Is Proxy Used’ field.
If you enable Proxy Redundancy (by setting EnableProxyKeepAlive=1 or 2),
the gateway can function with up to four Proxy servers. If there is no response
from the primary Proxy, the gateway tries to communicate with the redundant
Proxies. When a redundant Proxy is found, the gateway either continues
working with it until the next failure occurs or reverts to the primary Proxy (refer
to the ‘Redundancy Mode’ parameter). If none of the Proxy servers respond,
the gateway goes over the list again.
The gateway also provides real time switching (hotswap mode), between the
primary and redundant proxies (‘IsProxyHotSwap=1’). If the first Proxy doesn’t
respond to INVITE message, the same INVITE message is immediately sent
to the second Proxy.
Note 1: If ‘EnableProxyKeepAlive=1 or 2’, the gateway monitors the
connection with the Proxies by using keep-alive messages (OPTIONS or
REGISTER).
Note 2: To use Proxy Redundancy, you must specify one or more redundant
Proxies using multiple ’ProxyIP= <IP address>’ definitions.
Note 3: When port number is specified (e.g., domain.com:5080), DNS
NAPTR/SRV queries aren’t performed, even if ProxyDNSQueryType is set to 1
or 2.
