The following procedure describes how to configure alternative Tel-to-IP routing based on
IP connectivity.
 To configure alternative Tel-to-IP routing based on IP connectivity:
1. In the Tel-to-IP Routing table (see 'Configuring Tel-to-IP Routing Rules' on page 525),
add alternative Tel-to-IP routing rules for specific calls.
2. Open the Routing Settings page (Setup menu > Signaling & Media tab > Gateway
folder > Routing > Routing Settings):
Figure 24-7: Configuring Alternative Tel-to-IP Routing based on Connectivity
3. Under the Alternative Route group, do the following:
a. From the 'Enable Alt Routing Tel to IP' (AltRoutingTel2IPEnable) drop-down list,
select Enable to enable alternative Tel-to-IP routing based on IP connectivity.
b. From the 'Alt Routing Tel to IP Mode' drop-down list (AltRoutingTel2IPMode),
configure the IP connectivity reason for triggering alternative routing.
♦ Connectivity: Alternative routing is performed if a or SIP OPTIONS message
to the initial destination fails
♦ QoS: Alternative routing is performed if poor QoS is detected. QoS is
quantified according to delay and packet loss calculated according to
previous calls.
♦ Both (above)
c. (For Analog Interfaces Only) In the 'Alternative Routing Tone Duration' field,
configure the duration for which the device plays a tone to the Tel endpoint (for
analog interfaces) whenever an alternative route is used.
d. Enable the connectivity feature (see 'IP Destinations Connectivity Feature' on
page 541).
24.4.3 Alternative Routing Based on SIP Responses
The device can perform alternative routing based on the received SIP response code (i.e.,
4xx, 5xx, 6xx, or 8xx). If you have configured the response code in the Reasons for Tel-to-
IP Alternative Routing table, the device attempts to re-route the call to an alternative
destination, if configured. You can configure up to 10 SIP response codes in the Reasons
for Tel-to-IP Alternative Routing table.
