MultiVOIP FXS User Guide Technical Configuration

Note that Voice/FAX parameters are applied on a channel-by-channel basis. However, once you have established a set of Voice/FAX parameters for a particular channel, you can apply this entire set of Voice/FAX parameters to other channels by using the Copy Channel button and its dialog box.

The Voice/FAX Parameters fields are described in the tables below.

		Voice/Fax Parameter Definitions
Field Name	Values	Description
Default	--	When this button is clicked, all Voice/FAX parameters are set
		to their default values.
Select	1-24	Channel to be configured is selected here. The “-24” unit has
Channel	1-16	24 channels, the “-16” unit has 16 channels, and the “-8” unit
	1-8	has 8 channels.
Copy	--	Copies the Voice/FAX attributes of one channel to another channel.
Channel		Attributes can be copied to multiple channels or all channels at once.
Voice Gain	--	Signal amplification (or attenuation) in dB.
Input Gain	+31dB to	Modifies audio level entering voice channel before it is sent over the
	–31dB	network to the remote VOIP. The default & recommended value is 0 dB.
Output Gain	+31dB	Modifies audio level being output to the device attached to the voice
	to	channel. The default and recommended value is 0 dB.

DTMF Parameters
Duration	60 –	When DTMF: Out of Band is selected, this setting determines how
(DTMF)	3000 ms	long each DTMF digit ‘sounds’ or is held. Default = 100 ms.
DTMF	Out of	When DTMF Out of Band is selected, the MultiVOIP detects DTMF
In/Out of	Band, or	tones at its input and regenerates them at its output. When DTMF
Band	Inband	Inband is selected, the DTMF digits are passed through the
		MultiVOIP unit as they are received.
Out of Band	RFC	RFC2833 method. Uses an RTP mode defined in RFC 2833 to
Mode	2833,	transmit the DTMF digits.
	SIP Info	SIP Info method. Generates dual tone multi frequency
		(DTMF) tones on the telephony call leg. The SIP INFO
		message is sent along the signaling path of the call.
		You must set this parameter per the capabilities of the remote
		endpoint with which the voip will communicate. The
		RFC2833 method is the more common of the two methods.
