Permits the unit to send out the re-INVITE for T.38 or Fax Pass Through if a
fax tone is detected.
Default is Enabled
Selects jitter buffer type (Fixed or Adaptive) based on network conditions.
•
High (initial 200ms, min 40ms, max 600ms) Note: not all vocoders
can meet the high requirement.
•
Medium (initial 100ms, min 20ms, max 200ms).
•
Low (initial 50ms, min 10ms, max 100ms).
Selects SRTP mode to use ("Disabled", "Enabled but not forced", or

when remote (VoIP) side disconnects an active call. Default is No.
Allow user to configure if it will play busy/reorder tone before loop current
disconnect upon call fail. Default is No.
Configures the duration of voltage drop described in topic above.
