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 "Enabled and
forced"). Default is Disabled
It uses SDP Security Description to exchange key. Please refer to
SDES: https://tools.ietf.org/html/rfc4568
SRTP: https://www.ietf.org/rfc/rfc3711.txt
Adds crypto life time header to SRTP packets. Default is Yes.
Depends on standard phone type (and location).
Selects the caller id scheme, for example: Bellcore/Telcordia, ETSI-FSK ...
Defines the start and stop tones.
Disable analog phone's caller ID when receiving a call with "Anonymous",
"unavailable" or "unknown" in FROM header and without "Display info".
Note : This relies also on analog phone's design, some phones will still display
"unknown" with this feature enabled.
Default is No.
When this feature is set to Yes, device will replace the "+" sign at the beginning of
a number in the FROM
header. Default is No.
Reverses the polarity upon call establishment and termination. Default is No.
Allows the traditional PBX used with HT818 to apply this method for signaling call
termination. Method initiates short voltage drop on the line 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. HT818 support
a duration range from 100 to 10000 ms. Default value is 200.
Allow users to enable Pulse Dialing option under FXS Port. Default is No.
