Well what about if the caller is on hold for 20 minutes until he gets someone? Don't want to charge 20 minutes for being on hold.
Added after 17 minutes: Ahh this could work like this then:
- Setup Queue in Trixbox
- Have queue call technumber# or setup an extension with the technumber.
- forward the tech number to a2billing which in return will dial
[email protected].
- Set the incoming technumber call as a ring group. After 30 seconds, if no answer, hangup call.
- Since this is being triggered by the queue, it will continue trying until there is a connection.
So doing a stepping call, don't charge for first minute of the call and then set your per minute call charge thereafter or setup that the first 60 seconds are not charged.
