The alternative routing parameters are described in the table below.
Parameter

[AltRoutingTel2IPMode]
Version 6.4
Table A-63: Alternative Routing Parameters
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 = Internal routing table is used to locate a
redundant route (default).

[2] Proxy = Proxy list is used to locate a redundant route.
Note: To implement the Redundant Routing Mode mechansim,
you first need to configure the parameter
AltRouteCauseTEL2IP (Reasons for Alternative Routing table).
Enables the Alternative Routing feature for Tel-to-IP calls.

[0] Disable = Disables the Alternative Routing feature
(default).

[1] Enable = Enables the Alternative Routing feature.

[2] Status Only = The Alternative Routing feature is
disabled, but read-only information on the QoS of the
destination IP addresses is provided.
For information on the Alternative Routing feature, see
'Configuring Alternative Routing (Based on Connectivity and
QoS)' on page 326.
Determines the event(s) reason for triggering Alternative
Routing.

[0] None = Alternative routing is not used.

[1] Connectivity = Alternative routing is performed if a ping
or SIP OPTIONS message to the initial destination fails
(determined according to the AltRoutingTel2IPConnMethod
parameter).

[2] QoS = Alternative routing is performed if poor QoS is
detected.

[3] Both = Alternative routing is performed if either ping to
initial destination fails, poor QoS is detected, or the DNS
host name is not resolved (default).
Notes:

QoS is quantified according to delay and packet loss
calculated according to previous calls. QoS statistics are
reset if no new data is received within two minutes. For
information on the Alternative Routing feature, see
'Configuring Alternative Routing (Based on Connectivity and
QoS)' on page 326.

To receive quality information (displayed in the 'Quality
Status' and 'Quality Info.' fields in 'Viewing IP Connectivity'
on page 526) per destination, this parameter must be set to
2 or 3.
