Usage
Enter alaw for E-1 service.
Enter mulaw for T-1 service.
Usage
Normally select this value. PROGress asks the public network to
cut through the B-channel and let the caller hear tones such as
ringback 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
connected 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.
Usage
Use if you want to increase the length of the long timers.
Leave n if you want to use the default long timers.
