Mediant 500L MSBR
the device can operate in one of the following modes (configured by the
ProxyRedundancyMode parameter):
• Parking mode: The device continues operating with the redundant proxy (now
active) until the next failure occurs, after which it switches to the next redundant
proxy.
• Homing mode: The device always attempts to operate with the primary proxy. In
other words, it switches back to the primary proxy whenever it's available again.
If none of the proxy servers respond, the device goes over the list again.
Note: The device assumes that all the proxy servers belonging to the Proxy Set are
synchronized with regards to registered users. Thus, when the device locates an
available proxy using the Hot Swap feature, it does not re-register the users; new
registration (refresh) is done as normal.
The steps for configuring alternative Tel-to-IP routing based on SIP response codes are
summarized below.
 To configure alternative Tel-to-IP routing based on SIP response codes:
1. Configure SIP response codes (call failure reasons) that invoke alternative Tel-to-IP
routing:
a. Open the Reasons for Tel-to-IP Alternative Routing page (Configuration tab >
VoIP menu > GW and IP to IP > Routing > Alternative Reasons > Reasons
for Tel-to-IP).
b. Click Add; the following dialog box appears:
Figure 27-6: Reasons for Tel-to-IP Alternative Routing Table - Add Record
c. Configure a SIP response code for alternative routing according to the
parameters described in the table below.
d. Click Submit, and then save ("burn") your settings to flash memory.
Table 27-6: Reasons for Tel-to-IP Alternative Routing Table Parameter Descriptions
Parameter Description
Index
[AltRouteCauseTel2Ip_Index]
Defines an index number for the new table record.
Release Cause
CLI: rel-cause
[AltRouteCauseTel2Ip_ReleaseCause]
Defines a SIP response code that if received, the device
attempts to route the call to an alternative destination (if
configured).
2. Enable alternative routing based on SIP responses, by setting the 'Redundant Routing
Mode' parameter in the Proxy & Registration page to one of the following:
• Routing Table: Outbound IP Routing table is used for alternative routing.
• Proxy: Proxy Set redundancy feature is used for alternative routing.
3. If you are using the Outbound IP Routing table, configure alternative routing rules with
identical call matching characteristics, but with different IP destinations.
4. If you are using the Proxy Set, configure redundant proxies.
