Under asterisk, from your dialplan or an agi script you canput your calls (that has the same purpose)
in the same group.
This can be done using the GROUP* functions under asterisk.
- With GROUP() you can retrieve or set a group for the current channel
- With GROUP_COUNT() you can retrieve the total of live channel in that group
- With GROUP_LIST, you will get a list of group where the current channel is. So you can set put the same channel in multiple group to classify them.
- With GROUP_MATCH_COUNT, you can retrieve the number of live channels in that group matching the specifed regular expression.
