I'm a web designer by trade but I have a client who has asked me to help him out in an area that I know nothing about, hence I'm here!
My client uses an asterisk predictive dialer to make automated telephone calls using VOIP.
The client wants to allow his clients (medical offices), to use a web-interface whereby they login, and setup appointment reminders for their patients. This interface relays the information to the asterisk predictive dialer & it makes the phonecalls to the patients reminding them of their appointment time & date.
My main question is, what is the best way to accomplish this?
I spoke to a programmer friend briefly & he suggested the following:
Language: Any of PHP, Java, Ruby or Perl would probably do the job.
Security: HTTPS, secure application certificate.
Duration: 2 to 3 weeks
Cost: $100 an hour through an agency
Does this sound about right?
What other concerns should I be paying attention to?
Is their any advantage using one language over another?
I'm going to post this job, what requirements should I include that I may have overlooked?
Any info that will allow me make a more informed decision is really appreciated.
