Keep-Alive Feature for Persistent TLS Connections
Now in 3.2.2, the keep-alive feature has been added for persistent TLS connections
only. Administrators can configure this keep-alive feature using the new parameter
called “
sip persistent tls keep aliv
e”. When this feature is configured, the phone will
send keep-alive pings to the proxy server at configured intervals.
The keep-alive feature for persistent TLS connections performs the following func-
tionalities:
1.
After a persistent TLS connection is established or re-established, activate the keep-
alive, which will send CRLF to peer periodically.
2.
The phone will retry the connection automatically when a persistent TLS connection
is down.
3.
When a persistent TLS connection is re-established (primary is up or primary is down
and backup is up), refresh registration of the accounts associated with the connec-
tion.
4.
When a persistent TLS connection to primary is down, switch to backup if connection
to backup is working.
