Hello

At start i want to mention that i'm new to TAPI programming.
So as a newbie, i want to ask: is it possible to make analogue call using
tapi and panasonic pbx? The whole idea looks like this: simple app tries to
make list of  calls. If  one call reach destination number(call-receiver
picked up handset and said hello), application shows a monit to a caller who
picks up handset to talk.
Is it possible to to do?
Is it a problem that phones use analogue lines?

Thx for replies
Tom

Hi Tom,  sure.  Any TAPI device could do what you want.  Different
PBX's may handle it differently.  I do not remember how the Panasonic
does it, but usually you dial and it rings the phone for you to pick
up while it is ringing.  It assumes you are an agent at a desk and
need to manage the call.  In this case, the part where it senses a
voice connect and then rings you is the problem.  Some PBX's can
handle this directly, or you could use something like a CTI port and
that routes the call on connect to whatever phone you want.  But a lot
depends on how the call is handled when it leaves the PBX.  For
example, if you dial out on VoIP lines and hit a gateway, that gateway
could issue a connect and you really are not connecting to the end
point.  You said you were using analog lines, so the key thing is if
your device does voice recognition.

How almost all our clients do this is with an analog device.  You put
something like a Dialogic Card, SST Card, Hi-Phone etc, in front of or
behind the PBX.  It handles the call and does what it needs to do,
dial, talk via wave files to the called party, gets responses from
them, etc and then connects to whatever line you want it to.  We write
software to do this often as do clients who use our tools to do it.
