Cisco IP Phone Troubleshooting
Description
Select Normal or Based on SRV Port. The phone
creates an internal list of proxies returned in the DNS
SRV records.
If you select Normal, the list contains proxies ranked
by weight and priority.
If you select Based on SRV Port, the phone uses
normal, then inspects the port number based on the
first-listed proxy port.
Default: Normal
Set to Yes to enable the Dual registration/Fast Fall
back feature. To enable the feature you must also
configure the alternate proxy/alternate outbound proxy
fields in the Proxy and Registration section.
If set to No, the fallback happens immediately and
automatically. If the Proxy Fallback Intvl is exceeded,
all the new SIP messages go to the primary proxy.
If set to Yes, the fallback happens only when current
registration expires, which means only a REGISTER
message can trigger fallback.
For example, when the value for Register Expires is
3600 seconds and Proxy Fallback Intvl is 600 seconds,
the fallback is triggered 3600 seconds later and not
600 seconds later. When the value for Register Expires
is 600 seconds and Proxy Fallback Intvl is 1000
seconds, the fallback is triggered at 1200 seconds.
After successfully registering back to primary server,
all the SIP messages go to primary server.
