Parameter Description
Prefer Routing Table
[PreferRouteTable]
Determines if the device's internal routing table takes precedence over
a Proxy for routing calls.
[0] No = Only a Proxy server is used to route calls (default).
[1] Yes = The device checks the routing rules in the 'Tel to IP
Routing' table for a match with the Tel-to-IP call. Only if a match is
not found is a Proxy used.
Use Routing Table for Host
Names and Profiles
[AlwaysUseRouteTable]
Determines whether to use the device's internal routing table to obtain
the URI host name and optionally, an IP profile (per call), even if a
Proxy server is used.
[0] Disable = Don't use internal routing table (default).
[1] Enable = Use the 'Tel to IP Routing' table .
Notes:
This parameter appears only if the 'Use Default Proxy' parameter is
enabled.
The domain name is used instead of a Proxy name or IP address
in the INVITE SIP URI.
Always Use Proxy
[AlwaysSendToProxy]
Determines whether the device sends SIP messages and responses
through a Proxy server.
[0] Disable = Use standard SIP routing rules (default).
[1] Enable = All SIP messages and responses are sent to a Proxy
server.
Note: Applicable only if Proxy server is used (i.e., the parameter
IsProxyUsed is set to 1).
Redundant Routing Mode
[RedundantRoutingMode]
Determines the type of redundant routing mechanism to implement
when a call can’t be completed using the main route.
[0] Disable = No redundant routing is used. If the call can’t be
completed using the main route (using the active Proxy or the first
matching rule in the internal routing table), the call is disconnected.
[1] Routing Table = Internal routing table is used to locate a
redundant route (default).
[2] Proxy = Proxy list is used to locate a redundant route.
SIP ReRouting Mode
[SIPReroutingMode]
Determines the routing mode after a call redirection (i.e., a 3xx SIP
response is received) or transfer (i.e., a SIP REFER request is
received).
[0] Standard = INVITE messages that are generated as a result of
Transfer or Redirect are sent directly to the URI, according to the
Refer-To header in the REFER message or Contact header in the
3xx response (default).
[1] Proxy = Sends a new INVITE to the Proxy. Note: Applicable
only if a Proxy server is used and the parameter
AlwaysSendtoProxy is set to 0.
[2] Routing Table = Uses the Routing table to locate the destination
and then sends a new INVITE to this destination.
Notes:
When this parameter is set to [1] and the INVITE sent to the Proxy
fails, the device re-routes the call according to the Standard mode
[0].
When this parameter is set to [2] and the INVITE fails, the device
