{loop-start | ground-start}

or

{wink-start | immediate | delay-dial}

Router(config-voiceport)# signal loop-start

or

Router(config-voiceport)# signal wink-start

Defines the signal type to be used:

FXO and FXS voice ports:

loop-start Only one side of a connection can hang 
up. This is the default setting for FXO and FXS 
voice ports.

ground-start Allows both sides of a connection to 
place a call and to hang up. 

or

E&M voice ports:

wink-start—Indicates that the calling side seizes 
the line by going off-hook on its E-lead then waits 
for a short off-hook “wink” indication on its 
M-lead from the called side before sending address 
information as dual tone multifrequency (DTMF) 
digits. This is the default setting for E&M voice 
ports.

immediate—Indicates that the calling side seizes 
the line by going off-hook on its E-lead and sends 
address information as DTMF digits.

delay-dial—Indicates that the calling side seizes 
the line by going off-hook on its E-lead. After a 
timing interval, the calling side looks at the 
supervision from the called side. If the supervision 
is on-hook, the calling side starts sending 
information as DTMF digits; otherwise, the calling 
side waits until the called side goes on-hook and 
then starts sending address information.

Router(config-voiceport)# no shutdown

Router(config-voiceport)# exit
