Version 5.6 115 November 2008
SIP User's Manual 3. Web-Based Management
Parameter Description
re-routes the call according to the Standard mode [0]. If DNS
resolution fails, the device attempts to route the call to the Proxy. If
routing to the Proxy also fails, the Redirect / Transfer request is
rejected.
When this parameter is set to [2], the XferPrefix parameter can be
used to define different routing rules for redirected calls.
This parameter is disregarded if the parameter
AlwaysSendToProxy is set to 1.
Proxy / Registrar Registration Parameters
(Note: The proxy and registrar parameter fields appear only if 'Enable Registration' is enabled.)
Enable Registration
[IsRegisterNeeded]
Enables the device to register to a Proxy / Registrar server.
[0] Disable = device doesn't register to Proxy / Registrar (default)
server.
[1] Enable = device registers to Proxy / Registrar server when the
device is powered up and at every user-defined interval (configured
by the parameter RegistrationTime).
Note: The device sends a REGISTER request for each channel or for
the entire device (according to the AuthenticationMode parameter).
Registrar Name
[RegistrarName]
Registrar domain name. If specified, the name is used as the Request-
URI in REGISTER messages. If it isn't specified (default), the
Registrar IP address, or Proxy name or IP address is used instead.
The valid range is up to 49 characters.
Registrar IP Address
[RegistrarIP]
The IP address (or FQDN) and optionally, port number of the SIP
Registrar server. The IP address is in dotted-decimal notation, e.g.,
201.10.8.1:<5080>.
Notes:
If not specified, the REGISTER request is sent to the primary Proxy
server.
When a port number is specified, DNS NAPTR/SRV queries aren't
performed, even if DNSQueryType is set to 1 or 2.
If the RegistrarIP is set to an FQDN and is resolved to multiple
addresses, the device also provides real-time switching (hotswap
mode) between different Registrar IP addresses (IsProxyHotSwap
is set to 1). If the first Registrar doesn't respond to the REGISTER
message, the same REGISTER message is sent immediately to
the next Proxy. EnableProxyKeepAlive must be set to 0 for this
logic to apply.
When a specific Transport Type is defined using
RegistrarTransportType, a DNS NAPTR query is not performed
even if DNSQueryType is set to 2.
Registrar Transport Type
[RegistrarTransportType]
Determines the transport layer used for outgoing SIP dialogs initiated
by the device to the Registrar.
[-1] Not Configured (default)
[0] UDP
[1] TCP
[2] TLS
Note: When set to ‘Not Configured’, the value of the parameter
SIPTransportType is used.
