[asterisk-users] Play dial tone withou answer

[David Boyd]

Hi Arjan,

As I see it, the issue at hand is as follows:


You are attempting to provide a tandem service, meaning as you say no
charge to the originator unless the called party answers. However under
this circumstance you want to also provide a non-standard call treatment
to the line without an answer occurring. Standard treatment is to allow
the originating Switch/device to continue to provide the ringing
condition to the originators phone while the outbound attempt is being
completed. Very few carriers that utilize digital services (non-analog)
do not propagate audio back to the originating caller until such time as
an answer has been accomplished.


SO, this leads me to asking the following, how are the callers
originating calls into your system, what are they using for
authentication as well as indication of desired outbound calling data?
