Failover timmer in voice class server-group

[jacobmunson]

Hello all,

i am starting to use voice class server-group's for outbound dial-peer consolidation and would like to verify the failover process used. Take the following example.

voice class server-group 2020
ipv4 10.10.10.10 preference 1
ipv4 10.10.10.101 preference 2

if 10.10.10.10 is down or simply not responding how long will it take to fail over to 10.10.10.101? I have been unable to find documentation that talks about failover within the server-group. does it use the sip-ua timers?

Hi,

I don't have any official doc to confirm it but it does depend on the sip-ua timers. The default retry invite count is 6. However, you can tweak it like below

Conf t
Sip-ua
Retry invite 2

Using this we should see failover within 2 seconds rather than the 32 seconds for retry 6.

HTH
