About 4 years ago giqcass from the OBiHai forum with some help from me got a PHP script to initiate a GV callback for outbound calls. Yesterday I checked and the script has been kept current. I now have it working.
Here is a link to the script:
https://github.com/aaronpk/Google-Voice-PHP-API/blob/master/GoogleVoice.php
Below is my modified version.
I have the PHP script running under XAMPP web server on a Windows 7 machine.
To test the script, just enter the following in a web browser:
http://192.168.1.xx/gvcallback.PHP?dialnum=6235941000
Your DID number will ring. After you answer GV will call the number..
192.168.1.xx is the IP address of the computer running XAMPP Web Server.
6235941000 is the outbound number.
I have 2 ways to initiate a call from an ATA. I have a small Tropo PHP script to bridge SIP to HTTP. There is a OBi hack that uses ITSP Provisioning and a small script. Neither is ideal.
I tried running the full PHP script under Tropo, but I get a Permission error creating the cookie file. Does anybody know how to fix this error?
/No write FilePermission to /tmp/gvcookies.txt
Yate supports PHP scripts, but the setup is beyond my knowledge. Would anybody know how to run this script using Yate? Bill Simon? Any better ideas?
Both of these would be better than what I setup.
The XAMPP setup is fast and easy. Download and install the current XAMPP. Turn on Apache from the XAMPP Control Panel. Create file gvcallback.php using my modified script below and move it to folder XAMPP/htdocs. That's it!
Download XAMPP:
https://www.apachefriends.org/index.html
At the end of the script change Name to your GV name. Enter password. Change 1201xxxxxxx to you DID number (No + sign)
If anyone wants to see how I'm initiating calls, just ask.
