FreePBX – Custom FAX to email

FreePBX already has a FAX to email solution built into it., but it is a bit difficult (at least for me) to configure that on a embedded system like PIKA. So I decided to use some different script to do that job for me. I reused the same send mail script which used for Digium FFA to send FAX(Find it here). When you are using sendEmail script you can include the smtpserver address,username & password in the same script so that those will not be shown when you use Asterisk CLI for debugging. To include those credentials change the following lines in sendEmail.
Change the default SMTP Server under #Network
"server" => '', ## Default SMTP server

and change the eSMTP settings also

## eSMTP
"username" => '', ## Username used in SMTP Auth
"password" => 'password', ## Password used in SMTP Auth
"tls" => 'auto', ## Enable or disable TLS support. Options: auto, yes, no

To include custom dialplan in FreePBX we have to edit extensions_custom.conf. Here I have a dedicated FAX line which is connected to the 5th FXO port. All inbound calls will be forwarded to the context [from-pstn-custom] from there the dialplan will decide where the call go.,here if the call is on port 5 it will be forward to fax otherwise to IVR.

    I’m really impressed with your writing skills and also with the layout on your blog. Is this a paid theme or did you customize it yourself? Either way keep up the nice quality writing, it is rare to see a great blog like this one today.

    A little bit of knowledge goes a long way in all situations in life.

    Buying a car is no different! That means you need to read advice from experts, as detailed below, to ensure that when you shop for that car, you
    really know what you’re doing and how to get the best deal.

    I have been browsing online more than 4 hours today, yet I never
    found any interesting article like yours. It’s pretty worth enough for me.

    Personally, if all web owners and bloggers made good content as you did, the web will be
    a lot more useful than ever before.

      You can change the context from-pstn with from-pstn-custom in chan_dahdi.conf for each fax channel.
