	The default is NSE.
DTMF Tx Method	Select the method to transmit DTMF signals to the far end: InBand, AVT, INFO, Auto,
	InBand+INFO, or AVT+INFO. InBand sends DTMF using the audio path. AVT sends
	DTMF as AVT events. INFO uses the SIP INFO method. Auto uses InBand or AVT based
	on the outcome of codec negotiation.
	The default is Auto.
FAX Process NSE	To use the fax process NSE feature, select yes. Otherwise, select no.
	The default is yes.
Hook Flash Tx Method	Select the method for signaling hook flash events: None, AVT, or INFO. None does not
	signal hook flash events. AVT uses RFC2833 AVT (event = 16). INFO uses SIP INFO
	with the single line signal=hf in the message body. The MIME type for this message body
	is taken from the Hook Flash MIME Type setting.
	The default is None.
FAX Disable ECAN	If enabled, this feature automatically disables the echo canceller when a fax tone is
	detected. To use this feature, select yes. Otherwise, select no.
	The default is no.
Release Unused Codec	This feature allows the release of codecs not used after codec negotiation on the first call,
	so that other codecs can be used for the second line. To use this feature, select yes.
	Otherwise, select no.
	The default is yes.
FAX Enable T38	To enable the use of the ITU-T T.38 standard for faxing, select yes. Otherwise, select no.

	• caller only - SPA will detect FAX tone only if it is the caller
	• callee only - SPA will detect FAX tone only if it is the callee
	The default is caller or callee.
