Max Allowed Packet Loss for Alt
Routing [%]
configure voip > gateway routing
settings > mx-pkt-loss-4-alt-rte
[IPConnQoSMaxAllowedPL]
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%.
Max Allowed Delay for Alt
Routing
configure voip > gateway routing
settings > mx-all-dly-4-alt-rte
[IPConnQoSMaxAllowedDelay]

72.11.14 Alternative Routing Parameters
The alternative routing parameters are described in the table below.
Table 72-71: Alternative Routing Parameters
Parameter Description
3xx Use Alt Route Reasons
configure voip > sip-definition
settings > 3xx-use-alt-route
[UseAltRouteReasonsFor3xx]
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.
Redundant Routing Mode
configure voip > sip-definition
settings > redundant-routing-
m
[RedundantRoutingMode]
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.
