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 phone 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 field defines the layer 3 QoS parameter which can be the value
used for IP Precedence or Diff-Serv. Default value is 48
This setting includes two fields. The 802.1Q/VLAN Tag contains the
value used for layer 2 VLAN tag. Default setting is blank. And
802.1p priority value contains the value of the priority value.
This parameter controls whether the IP phone supports the DNS
SRV route function.
If the HandyTone ATA has an assigned PSTN telephone number,
then this field will be set to "Yes". Otherwise, set it to "No". If
"Yes" is set, a "user=phone" parameter will be attached to the
"From" header in SIP request.
This parameter controls whether the IP phone needs to send
REGISTER messages to the proxy server. The default setting is
"Yes".
Default is No. If set to yes, the SIP user will be unregistered on
reboot.
