UCM6100 Series User Manual
Version 1.0.18.13
Select DTMF mode to send DTMF. The default setting is RFC2833. If "Info" is
selected, SIP INFO message will be used. If "Inband" is selected, 64-kbit codec
PCMU and PCMA are required. When "Auto" is selected, "RFC2833" will be used
if offered, otherwise "Inband" will be used. The default setting is "RFC2833".
During an active call, if there is no RTP activity within the timeout (in seconds),
the call will be terminated. The default setting is no timeout.
Note:
This setting doesn't apply to calls on hold.
When the call is on hold, if there is no RTP activity within the timeout (in seconds),
the call will be terminated. This value of RTP Hold Timeout should be larger than
RTP Timeout. The default setting is no timeout.
This feature can be used to avoid abnormal call drop when the remote provider
requires RTP traffic during proceeding.
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.
When configured, RTP keep-alive packet will be sent to remote party at the
configured interval. If set to 0, RTP keep-alive is disabled.
