Grandstream Networks 486 Authentication Password, Name, Preferred Vocoder, G723 Rate, Fax Mode

HandyTone-486 User Manual		Grandstream Networks, Inc.
Authentication Password	Account information, password for ATA to register to (SIP) servers of ITSP.
Name	Field for user to put in additional information to be displayed when calling, like caller ID.
Preferred Vocoder	The HandyTone ATA supports up to 7 different codec	types including G.711 A/U
	law，G.723.1, G.726, G.728, G.729A/B, iLBC. Depending on the product model, some of
	these codecs may not be provided in standard release.
	A user can configure codecs in a preference list that will be included with the same preference
	order in SDP message. The first codecs in this list can be entered by choosing the appropriate
	option in “Choice 1”. Similarly, the last codecs in this list can be entered by choosing the
	appropriate option in “Choice 6”.
G723 Rate:	This defines the encoding rate for G723 codec. By default, 6.3kbps rate is chosen.
iLBC frame size:	This sets the iLBC packet frame size in 20ms or 30ms. Default is 20ms. For Asterisk PBX,
	30ms might need to be set.
iLBC payload type:	This defines payload time for iLBC. Default value is 98. The valid range is between 96 and
	127. For Asterisk PBX, 97 might need to be set.
Silence Suppression	This controls the silence suppression/VAD feature of G723 and G729. If set to “Yes”, 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.
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 codec in the
	above codec Preference List or the actual used payload type negotiated between the 2
	conversation parties at run time.
	e.g., if the first codec 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 codec
	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 codec 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. Please be careful when massage those parameters.
Fax Mode	T.38 (Auto Detect) FoIP by default, or Pass-Through (must use codec PCMU/PCMA)
Layer 3 QoS	This field defines the layer 3 QoS parameter which can be the value used for IP Precedence or
	Diff-Serv or MPLS. Default value is 48.
Layer 2 QoS	This contains the value used for layer 2 VLAN tag. Default setting is blank.
Use DNS SRV:	Default is No. If set to Yes the client will use DNS SRV to lookup for the server
User ID is Phone	If the HandyTone ATA has an assigned PSTN telephone number,
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
SIP Registration	This parameter controls whether the HandyTone ATA needs to send REGISTER messages to
	the proxy server. The default setting is “Yes”.
