I need some (help, advice, link, script) for solution for my issue. Make long story short - I need that extension recall to caller if its no answer. Proly some dialplan, luascript or something else.
Would almost certainly require a lua script for a function like that.
The fax sending script might point someone in the right direction to build a script from. I seem to remember there is a retry option in one of the lua scripts related to Faxes
I'm not sure that it will work for me. When a client is on hold for a few minutes the call will be ended by the system and have to call him back once the line is free.
