Built-in Dynamic Features

The FEATURE and FEATUREMAP dialplan functions allow you to set some features.conf options on a per channel basis.

Note

To see what options are currently supported, look at the FEATURE and FEATUREMAP function descriptions. These functions were added in Asterisk 11.

At this time the functions do not work with custom features. Those are set with a channel variable as described in the Custom Dynamic Features section.

Set the parking time of this channel to be 100 seconds if it is parked

exten => s,1,Set(FEATURE(parkingtime)=100)
 same =>   n,Dial(SIP/100)
 same =>   n,Hangup()

Set the DTMF sequence for attended transfer on this channel to *9

exten => s,1,Set(FEATUREMAP(atxfer)=*9)
 same =>   n,Dial(SIP/100,,T)
 same =>   n,Hangup()
