To use the Continue code to extend a DISA call:
1. An external call connects to an external number (either by transferring with Tandem Trunking or by
DISA caller).
2. After the programmed time (Program 25-07-07), a warning tone is heard and the user dials the
Continue code (Program 20-28-01) to extend the conversation.
3. After the programmed time (Program 20-28-03), the warning tone is heard again. After the
programmed time (Program 25-07-08), the call is disconnected if the Continue code is not dialed
again.
