RTP Timeout
During an active call, if there is no RTP activity before the configured timeout,
the call will be terminated. The default setting is no timeout.
Note: This setting does not apply to calls on hold.
RTP Hold Timeout
When the call is on hold, if there is no RTP activity before the configured
timeout, the call will be terminated. This value of RTP Hold Timeout should be
larger than RTP Timeout. The default setting is no timeout.
RTP Keep-alive
This feature can be used to avoid abnormal call drop when the remote provider

For example, when the call goes into voicemail and there is no RTP traffic sent
out from UCM, configuring this option can avoid voicemail drop.
