Call Control Commands

The following table describes the Call Control Commands.

AT!T1=n	Incoming Call Assignment (first directory number). Specifies the type of incoming
	ISDN calls that DIVA T/A can accept on the first directory number.
	n=0	Only available on DIVA T/A models that have an analog device port. Specifies that
		all analog device voice calls (e.g. telephone, fax/modem over ISDN) are directed
		to your analog device port.
		This option does not permit you to receive ISDN data calls. If you want to receive
		ISDN data calls, make sure that one Directory Number has n=1 as the Incoming
		Call Type.
	n=1	Default for models with analog device port.
		With Analog Device Port: Specifies that all regular ISDN data calls are directed to
		your PC, and that all analog device calls (e.g. ordinary phone calls, or fax/modem
		over ISDN calls) are directed to your analog device port
		Without Analog Device Port: Specifies that all regular ISDN data calls are directed
		to your PC. This option does not permit you to receive analog calls.
	n=8	Reserved for use by RVS-COM. Do not set.
	n=9	Reserved for use by RVS-COM. Do not set.
		These last two settings are automatically altered when a FAX application issues
		a +FCLASS command. This ensures incoming and outgoing calls are compatible
		with the necessary fax class.
AT!T2=n	Incoming Call Assignment (second directory number). Specifies the type of
	incoming ISDN calls that DIVA T/A can accept on the secondary directory number.
	n=0	Only available on DIVA T/A models that have an analog device port. Specifies that
		all analog device voice calls (e.g. telephone, fax/modem over ISDN) are directed
		to your analog device port.
		This option does not permit you to receive ISDN data calls. If you want to receive
		ISDN data calls, make sure that one Directory Number has n=1 as the Incoming
		Call Type.
	n=1 With Analog Device Port: Specifies that all regular ISDN data calls are directed to
		your PC, and that all analog device calls (e.g. ordinary phone calls, or fax/modem
		over ISDN calls) are directed to your analog device port.
		Without Analog Device Port: Specifies that all regular ISDN data calls are directed
		to your PC. This option does not permit you to receive analog calls.
	n=8	Reserved for use by RVS-COM. Do not set.
	n=9	Reserved for use by RVS-COM. Do not set.
