This field contains the number of voice frames to be transmitted in a single
packet. When setting this value, the user should be aware of the requested
packet time (used in SDP message) as a result of configuring this parameter.
This parameter is associated with the first vocoder in the above vocoder
Preference List or the actual used payload type negotiated between the 2
conversation parties at run time.
e.g., if the first vocoder is configured as G723 and the "Voice Frames per TX"
is set to be 2, then the "ptime" value in the SDP message of an INVITE request
will be 60ms because each G723 voice frame contains 30ms of audio.
Similarly, if this field is set to be 2 and if the first vocoder chosen is G729 or
G711 or G726, then the "ptime" value in the SDP message of an INVITE
request will be 20ms.
If the configured voice frames per TX exceeds the maximum allowed value, the
HandyTone ATA will use and save the maximum allowed value for the
corresponding first vocoder choice. The maximum value for PCM is 10(x10ms)
frames; for G726, it is 20 (x10ms) frames; for G723, it is 32 (x30ms) frames;
for G729/G728, 64 (x10ms) and 64 (x2.5ms) frames respectively.
This defines the encoding rate for G723 vocoder. Default setting is 6.3kbps.
This sets the iLBC size in 20ms or 30ms
between 96 and 127.
when a silence is detected, small quantity of VAD packets (instead of audio
packets) will be sent during the period of no talking. If set to "No", this feature
is disabled.
T.38 (Auto Detect) FoIP by default, or fax Pass-Through.
Default is No. Use only if proxy supports 484 response
Sets the prefix added to each dialed number
This parameter allows users to configure the "#" key to be used as the "Send"
(or "Dial") key. If set to "Yes", pressing this key will immediately trigger the
sending of dialed string collected so far. If set to "No", this "#" key will then be
included as part of the dial string to be sent out.
Indication will be sent periodically.
If this parameter is set to "Yes", user ID will be sent as anonymous, essentially
blocking the Caller ID from displaying.
If this parameter is set to "Yes", the configuration update via keypad is
disabled.
