DTMF You may need to change the DTMF configuration if you cannot interact with interactive
voice response systems (auto attendants, voice-activated menus, and so on).
RTP This timer controls how calls are disconnected when Bria determines that there is a
problem with the call and the other party has probably disappeared (assuming that you
have not yourself detected the problem and hung up manually).
Typically, the timer is enabled. It is recommended that you not disable it.
You can change the length of the timer, but do not set it to less than 30 seconds.
Use old style hold Change this setting only if your VoIP service provider advises you to do so.
