I cannot reconnect to a call on Hold/The call does not terminate
If you put a call on hold and then have a problem trying to un-hold or reconnect to a
call during a conference or transfer, the caller may have dropped. This can happen if
the other caller has had an interruption with their network connection.
In most cases, the call will time out and the call will terminate automatically. In cases
where the call is not automatically terminated, press the EndCall softkey to terminate
the call.
If you are in the process of transferring a call or in a conference, press the Split
softkey to split the calls, then use the Shuttle softkey to switch to the dropped call, and
press the EndCall softkey to terminate that call.
