Failover During Call - Grandstream Networks UCM6300 Series High Availability User Manual

FAILOVER DURING CALL

When the active server encounters failure, if there is ongoing call on the active server, the switchover
process will only cause a few seconds of audio cutoff and then it will be recovered automatically.
Notes:
•
Currently, if the call is using UDP as transport method, the call can be recovered after switchover.
However, if the call is using TCP as transport method, the call cannot be recovered after switchover.
•
Point-to-point calls such as audio call or audio meeting can be recovered after switchover. However,
for calls using ring group, call queue and other call features and services, the call will not be
automatically recovered.
