digits—the caller’s number—and dial number identification service (DNIS) digits—the called

trunks as well as basic R1 and FGD Terminating protocol.

•DT—Immediate start and basic DTMF and dial-pulse trunks.

•MD—North American MF FGD EANA and EAIN, which allows VISM to be at the end office, the

carrier, or the tandem side of the circuit.

•MO—FGD Operator Services Signaling, outgoing trunks only.

•BL—DTMF and dial pulse (DP) basic PBX trunks.

RFC 2833 Support
