[asterisk-users] recommended application for salesman using asterisk

[Yu Safin]

Hi, I am a salesman currently using asterisk to contact my customers.
So far, I have asterisk connected to two PSTN analog lines where I
only receive phones calls.
Then, I have asterisk connected to a VoIP service company for
terminating my phone calls.
I also kept one PTSN phone line to place calls to my cellular when I
am on the road.  This is done by giving the caller an option to find
me on my cellular.
I started to tinker with my PC and I can now receive and place calls
using a soft-phone (iaxclient).  Then I started to wonder if there is
an application that will allow me to use a friendly WEB interface
along side with my soft-phone to quickly place phone calls from an
address book and when I call arrives, to bring up information about
the caller if present in my address book.
I also conceived the idea that I might not even have the imagination
that some members of this list may have in terms of how else I can be
exploiting asterisk e.g. callback from messages left.  Another one is
a more sophisticated find-me service that I can manage from a WEB
interface.
I am open to ideas and suggestions.  Please show me where to go.
Remeber, if I spend too much time as an engineer I go hungry.  I need
to be in front of people selling my company services and not tinkering
with applications.
Thank you.
