Resilience and Survivability

To allow for a stable operation even in the presence of network or server failure, OpenStage
phones have the capability to switch to a fallback system. The switchover is controlled by vari-
ous configurable check and timeout intervals.
In survivability mode, it is expected that some features and functionality will not be available.
The user will be informed by a message in the Call View display.
3.4.9.1

TLS Connectivity Check

A regular check ensures that the TLS link to the main SIP server is active. When the Connec-
tivity check timer is set to a non-zero value, test messages will be sent at the defined interval.
If the link is found to be dead, the phone uses DNS SRV to find another SIP server.
If TLS is to be used, please ensure that the SIP over TLS connection between pho-
>
nes and sever work properly.
