Alternative Routing Parameters

The alternative routing parameters are described in the table below.
Parameter
Web: 3xx Use Alt Route Reasons
CLI: configure voip/sip-definition
advanced-settings/3xx-use-alt-route
[UseAltRouteReasonsFor3xx]
Web/EMS: Redundant Routing
Mode
CLI: redundant-routing-m
[RedundantRoutingMode]
[DisconnectCallwithPIifAlt] Defines when the device sends the IP-to-Tel call to an
User's Manual
Defines the packet loss (in percentage) at which the IP
connection is considered a failure and Alternative Routing
mechanism is activated.
The default is 20%.
Defines the transmission delay (in msec) at which the IP
connection is considered a failure and the Alternative Routing
mechanism is activated.
The range is 100 to 10,000. The default is 250.
Table 51-68: Alternative Routing Parameters
Defines the handling of received SIP 3xx responses regarding
call redirection to listed contacts in the Contact header.

[0] No = (Default) Upon receipt of a 3xx response, the
device tries each contact, one by one, listed in the Contact
headers, until a successful destination is found. However, if
a contact responds with a 486 or 600, the device does not
try to redirect the call to next contact, and drops the call.

[1] No if 6xx = Upon receipt of a 3xx response, the device
tries each contact, one by one, listed in the Contact
headers. However, if a 6xx Global Failure response is
received during this process (e.g., 600 Busy Everywhere)
the device does not try to redirect the call to the next
contact, and drops the call.

[2] Yes = Upon receipt of a 3xx response, the device
redirects the call to the first contact listed in the Contact
header. If the contact responds with a SIP response that is
defined in the Reasons for Tel-to-IP Alternative Routing
table, the device tries to redirect the call to the next contact,
and so on. If a contact responds with a response that is not
configured in the table, the device does not try to redirect
the call to the next contact, and drops the call.
Determines the type of redundant routing mechanism 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 Routing table), the call is
disconnected.

[1] Routing Table = (Default) Internal routing table is used
to locate a redundant route.

[2] Proxy = Proxy list is used to locate a redundant route.
Note: To implement the Redundant Routing Mode
mechanism, you first need to configure the parameter
AltRouteCauseTEL2IP (Reasons for Alternative Routing table).
