[asterisk-users] SLA for DAHDI FXO - Emulating Key System Functionality

[bakko]

Hi

For this scenario you can use the group and group_count functions and create
a hint dialplan like this:

exten => trunkname,hint,custom:trunkname

When you reach the maximum number of available channels set the hint in use:

Set(DEVICE_STATE(Custom:confcorso)=INUSE)

To remove:

Set(DEVICE_STATE(Custom:confcorso)=NOT_INUSE)

After this, configure BLF on the phone top subscribe trunknumber "extension"

Regards
