we are planning to start fax2email service. looking for developer that already has a built solution with all standard feature. both front end and back end required. likely tools will be mysql , php , apache, asterisk . service will be similar to efax , trustfax
Sometime ago I delivered a very similar solution based on analog fax received over a T1 trunk and redelivered to email account as an attachment. Solution uses Asterisk, CentOS, Apache, postfix, and HylaFax and still working without almost no downtime.
Web Interface was Java based but I think I could redone it on PHP.
Please feel free to ask for more details.
