Usage
Normally select this value. PROGress asks the public network to
cut through the B-channel and let the caller hear tones such as ring-
back or busy tone provided over the non-ISDN trunk.
ALERTing causes the public network in many countries to play
ringback tone to the caller. Select this value only if the DS1 is con-
nected to the public network, and it is determined that callers hear
silence (rather than ringback or busy tone) when a call incoming
over the DS1 interworks to a non-ISDN trunk.
