[asterisk-users] Post Dial Delay + Playtones

[Morgan Gilroy]

Can anyone give me some pointers on the following, in our setup (ast
1.6.3) we use international carriers to terminate calls for a
callingcard system, we have an issue where there can be a very long
delay after dialing but before the far end begins to ring.

I would like to play a tone every second during this period (before
ringing) but then cut off the tone once the far end either sends ringing
or progress in band (183).

Iv tried using Progress() and Playtones() before the dial but Playtones
cuts off as soon as i hit Dial. Iv tried using the Sip/xxx&Sip/xxx trick
to get Playtones to continue (which kinda works) unfortunately this also
over writes the far end ringing, so the user only hears the tone every
second until the far end answers.

I have tried a lot of things but can't seem to get the exact behaviour
we want.
