Forced Trunk Disconnect
This feature only works on analog trunk. ISDN trunks do not have the Forced Trunk Discon-
nect available.
Transfer
Transferred calls on DISA, DID, ISDN trunks, or from the VRS can display the reason a call
is being transferred (Call Forward, Busy, No Answer, or DND).
Networking
Trunk-to-Trunk transfer of ISDN PRI calls will work only when the two trunks are in the
same system.
Refer to the ISDN-BRI Manual (P/N TBD) and ISDN-PRI Manual (P/N 0893212) for the specifics.
