Use this procedure to define the signaling types needed in your telephony
environment.This procedure applies to Channel associated signaling (CAS)
only.
Note: You must use the same common channel signaling (CCS) protocol
for all the channels on a trunk. Therefore, you do not need a
Signaling
Type definition when using CCS protocols. If you are using a CCS protocol,
skip this section and go to
Defining channel groups.
For an introduction to signaling types, see Supporting one or more protocols.
