Atlantis Land A02-RAV211 manual Echo Cancellation Tail Length Setting the Tail Length

VoIP ROUTER ADSL

Echo Cancellation Tail Length: Setting the Tail Length.

Configure DTMF Relay: DTMF (Dual Tone Multi Frequency).

None: selecting none for sending DTMF tone in original audio form.

RFC 2833: sending voice with RTP packets

Configure Hook Flash Time: This parameter specifies the maximum time in mSec of Hook flash. For a Hook flash to be detected , there should be an on-hook followd by an off-hook within “ Hook Flash Max Time” mSec.

Configure Debounce Time: There are two parameters to be configured here.

OnOffDebounce Time: A delay in mSec before informing on an off-hook event to ensure it is not a spike. If during that time an on-hook event is received , the two events will be ignored. If 0 , no debounce will be done.

OffOnDebounce Time: A delay in mSec before informing on an on-hook event to ensure it is not a spike. If during that time an off-hook event is received , the two events will be ignored. If “Hook Flash Max Time” is configured , it MUST be more than OffOnDebounce. If it is 0 , no debounce will be done.

Codec Preference: Set the priority of voice compression in terms of voice codec for outgoing message and indication of incoming message accompanied with codec preference information. Priority 1 owns the top priority.

G.711U / G.711A: G.711U and G.711A are the basic non-compressed encoder/decoder technique. You can have very good sound quality but 64kbps bandwidth is needed.

G.729A: Using G.729A to encoder/decoder voice information into a single packet reduces the bandwidth consumption (8kbps only) while you still can have good sound quality.

Note: Codec priority is selected using a drop-down box. If two codec types are assigned the same priority, then the priority is assigned in the order as G711U > G711A > G729 in the decreasing order of priority. For example, if the user selects 1, 2, 2, for G711U, G711A, and G729A respectively, the application will assign priority as 1, 2, and 3 for G711U, G711A, and G729A respectively
