Click-to-call url parameters

[eiznem]

Hello fellow OBi users. This is my first post. I know there aren't any stupid questions, just stupid people asking questions (me). With that, here's the problem I'm looking to solve:

Since the Google Chrome browser extension for Google Voice click-to-call (converts phone numbers in web pages to URLs that are clickable to launch a call via your connected phone of choice) no longer works, I've been looking for another solution that will initiate the call from my browser by ringing my OBi1062 and then connecting to the phone number I clicked.

There is a browser extension (https://chrome.google.com/webstore/detail/url-networks-number2url/lndpiehcijmlgooadkonganjdnnaojhc) that would allow me to configure a URL with parameters, however I cannot seem to locate any parameters that would accomplish this on my OBi1062. I would expect something like http://192.168.1.100?CallPhoneNumber=5555555555&Line=sp1 (where 192.168.1.100 represents my OBi's IP address). Does anyone know of parameters I can use to initiate a call from my browser that will ring to my OBi on sp1 then dial out to the phone number I clicked when I answer that line?

Thanks in advance.

There are 2 methods you can use.

Ignore the OBi setup at the end of the post.

For those that want the Google Voice click-to-call function in Google Chrome, follow these modified instructions from azrobert (taken from post at http://www.obitalk.com/forum/index.php?topic=14632.0) as well as my additional instructions below:

1. Obtain a SIP DID (CallCentric has free NY state DIDs with free inbound) and set it up on your GV account as a forwarding number as well as on your OBi device ...mine is an OBi1062).

2. Setup XAMPP (download here: https://www.apachefriends.org/index.html | install instructions here: https://undsgn.com/xampp-tutorial/ ...ignore the WordPress stuff but be sure to start Apache from the XAMPP Control Panel after installation)

3. Copy and paste the script below into Notepad. At the end of the script change Name to your GV name, change password to your GV password, and change 1xxxxxxxxxx to your CallCentric DID number (No + sign).

4. Save the file as gvcallback.php (Do NOT save it as a txt file, use type ALL FILES) then move the gvcallback.php file to folder XAMPP/htdocs.

5. Test the script, just enter the following in a web browser: http://192.168.1.xx/gvcallback.PHP?dialnum=8005551212 (192.168.1.xx is the IP address of the computer running XAMPP Web Server.
8005551212 is the number you're wanting to call). Your DID number will ring. After you answer, GV will call the number you specified.

6. Install URL Networks number2url Chrome Extension (https://chrome.google.com/webstore/detail/url-networks-number2url/lndpiehcijmlgooadkonganjdnnaojhc)

7. Alter the options of the number2url extension with the following:
     Profile: International (outside Australia)
     Mode: Active (left click actions)
     Protocol: Custom URL
     Custom URL: http://$1/gvcallback.PHP?dialnum=$0&outgoing_uri=$2
     Phone IP: 192.168.1.xx (this will be the IP address of the computer running XAMPP)
     Link Target: Default

Be sure to click save when you've finished. Now go find a phone number online and click it to call. This will work great for sales people using CRMs to call sales leads, etc.

Thank you for your help on this azrobert!
