Hunt Groups
Calls can be forwarded automatically to the first available line.
Battery Polarity Reversal
Detection and Initiation
Detection and Initiation
Detection of disconnect supervision and far-end answer supervision via battery polarity
reversal provides a robust method of providing supervisory disconnect especially for
loop start signaling on FXS and FXO interfaces (12.1(2)T and later Cisco IOS Plus
images support battery polarity reversal on the VIC-2FXS, VIC-2FXO-M1 and
VIC-2FXO-M2 VICs).

Supervisory Disconnect
Signalling protocols such as loop-start do not provide means for quickly detecting
when the call initiation is terminated prior to call connection. Supervisory disconnect
quickly makes this determination and frees valuable resources for other calls.
