Sending fax via smartphones\android

Question

I am searching for a way to send fax via android phone. Sending fax uses converting voice to data, its been done for years on land wire phones by calling to remote fax playing the voice we all familier with and thats it. So how\is it possible that the android phone will call to othe fax and convert some img file to voice and will play this voice one it called to other fax?

Answer 2

FAX is a bi-directional protocol that goes through several stages of handshake before the actual image data is sent. Even if you could write an Android app to listen and "speak" the correct audio tones, the QOS (quality of service) of cellular voice is lower than that of land lines and would not succeed. The only FAX capability offered by some mobile service providers allows you to receive a fax to your mobile number and it will get stored to voicemail. From there you can forward the message to a land line to print it out at a later time.

As others have mentioned, your best bet is to use a web (cloud) based API for sending and receiving faxes.
