[Asterisk-Users] time of waiting in queues

[Daniel Cubero Salas, Ing.]

We have implement a IVR with CTD+CDR and queues, all on asterisk. Just for
statistics, we need to save the time which one client was waiting in queue.
Someone knows asterisk has a function than it can be load in a module
(programming by us) or if a module with this function was developtment.

Thanks in advance

Daniel
