30 
Voice Frames per 
TX 
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.  
Fax Mode 
T.38 (Auto Detect) FoIP by default, or Pass-Through (must use codec 
PCMU/PCMA) 
Dial Plan Prefix 
Sets the prefix added to each dialed number 
Use # as 
Send Key 
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. In this case, this key is essentially 
equivalent to the “(Re)Dial” key. If set to “No”, this “#” key will then be 
included as part of the dial string to be sent out.  
Subscribe for MWI:  Default is No. When set to “Yes” a SUBSCRIBE for Message Waiting 
Indication will be sent periodically. 
Send Anonymous 
 
If this parameter is set to “Yes”, the “From” header in outgoing INVITE 
message will be set to anonymous, essentially blocking the Caller ID from 
displaying. 
Special  Feature 
Default is Standard. Choose the selection to meet some special requirements 
from Soft Switch vendors like Lucent FS5000 Simple Endpoint,  CBCOM, etc.
