User's Manual
Defines the transport type for communicating with the Proxy server.

[0] UDP

[1] TCP

[2] TLS

[-1] = Undefined
Note: If this parameter is not defined, the settings of the global
parameter SIPTransportType is used.
Defines an arbitrary name to easily identify the Proxy Set.
The valid value is a string of up to 20 characters.
Defines the DNS query record type for resolving the Proxy server's
host name into an IP address.

[-1] = DNS resolving is done according to the settings of the
global parameter, Proxy DNS Query Type.

[0] A-Record = (Default) A-record DNS query.

[1] SRV = If the Proxy address is configured with a domain
name without a port (e.g., domain.com), an SRV query is done.
The SRV query returns the host names (and their weights). The
device then performs DNS A-record queries per host name
(according to the received weights). If the configured Proxy
address contains a domain name with a port (e.g.,
domain.com:5080), the device performs a regular DNS A-record
query.

[2] NAPTR = NAPTR query is done. If successful, an SRV
query is sent according to the information received in the
NAPTR response. If the NAPTR query fails, an SRV query is
done according to the configured transport type. If the
configured Proxy address contains a domain name with a port
(e.g., domain.com:5080), the device performs a regular DNS A-
record query. If the transport type is configured for the Proxy
address, a NAPTR query is not performed.
Note: An SRV query can return up to four host names. For each
host name, the subsequent DNS A-record query can be resolved
into up to 15 IP addresses. However, the device supports up to 30
DNS-resolved IP addresses. If the device receives more than this
number of DNS-resolved IP addresses, the device uses the first 30
IP addresses in the received list, and ignores the rest.
Enables the device's Proxy Keep-Alive mechanism, which checks
communication with the Proxy server.

[0] Disable (default).

[1] Using Options = Enables the Proxy Keep-Alive mechanism
using SIP OPTIONS messages. The device sends these
messages every user-defined interval, configured by the 'Proxy
Keep Alive Time' parameter. If the device receives a SIP
response code that is also configured in the 'Keep-Alive Failure
Responses' parameter (below), the device considers the Proxy
as down. You can also configure whether to use the device's IP
address or string name ("gateway name") in the OPTIONS
message (see the UseGatewayNameForOptions parameter).

[2] Using Register = Enables the Proxy Keep-Alive mechanism
using SIP REGISTER messages. The device sends the
REGISTER message every user-defined interval, configured by
the RegistrationTime parameter (Gateway application) or
