Manager blocks you from changing this field unless the port is busied out or unadministered.

blocks you from changing this field unless the port is busied out or unadministered.

Interworking Message
This field determines what message Communication Manager sends when an incoming ISDN
trunk call interworks (is routed over a non-ISDN trunk group).
Valid entries
PROGress
ALERTing
Usage
Leading zeroes considered significant and not ignored.
Usage
If set to y, the SPID field must not be blank. Avaya Communication
Manager blocks you from changing this field and the SPID field unless
that port is busied out or unadministered.
If set to n, the SPID and Endpt ID fields must be blank.
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.
