[Freeswitch-users] Need help on a calling card service

[Alfred Stainer]

Hi all, we are developing a calling card service based on Freeswitch and we
have the necessity to implement the following features but we have not found
a way to do that:
we want that the first 10 seconds of the call are free of charge for the
caller.
This is not only a billing issue because most of our customers don't call a
free number so we want that the connect to the caller is sent only after 10
seconds we receive the connect from called.
We bridge the inbound leg with the outbound leg but we are not capable to
delay the propagation of the connect.
The perfect solution will be that when we receive the connect from outgoing
leg we send the preanswer on incoming leg and 10 second after that we send
the connect.
There is a way to do that? Any advice?

Alfred
