Custom Google Voice Widget

  • March 22nd,
  • by Razvan Gavril

Google Voice has very usefull click to call widget that you can add on your website but .. it’s flash it’s big and I don’t like it. I wanted something that I can customise and that can run without flash (ex. on iPhone) so I looked under the hood to see if I can create a html only widget, and it’s actually quite easy.

First you need to login in your google voice account and create a call widget from the Settings page. This is required as it creates a uniquid that we will use later. After creating the widget, copy the Embed string into a text editor. We’re going to extract only what we need from there. For example my embed string looks like this:

<object type="application/x-shockwave-flash" data="" width="230" height="85">
<param name="movie" value="" />
<param name="wmode" value="transparent" />
<param name="FlashVars" value="id=4563a8e24f4009bcaf7122437e2f9bc0b15c192e&style=0" />

What we will use from all this is only the id flash parameter and the client server from google.

And now let’s create a html equivalent of the flash code. It’s actually quite simple as the flash doesn’t do anything else than sending a post to google server with some parameters.

<form method="post" action="">
<input type="hidden" name="buttonId" value="4563a8e24f4009bcaf7122437e2f9bc0b15c192e" />
Caller Number:
<input type="text" name="callerNumber" />
<br />
Caller Name :
<input type="text" name="name" />
<br />
Show Caller Number :
<input type="checkbox" value="1" name="showCallerNumber" checked="checked" />
<br />
<button type="submit">Call Me</button>

Of course you should create your custom form, style it with css and it’ll look great. I recommend posting the form with ajax else the user is redirected to google’s page after clicking your button, is up to how you decide to use it.

    I am getting what looks like an error while using your demo:


    Did you disable your demo? I love this idea, but am having a problem seeing it in action.

    I think that wordpress removed my input type hidden when I last modified the post, that’s why you where seeing the ok=false. I’ve corrected it now.

    Unfortunately I don’t think is possible to call a international number with google voice widget.

    If you have an available linux server you can use an asterisk or freeswitch with a voip provider to do that.

    Works great! Only, like you said, the user’s redirected to the Google “ok=true” page afterward, which is a bummer. I know nothing about Ajax, and my site is run on the Blogger platform. Do you know of any way to use Blogger’s APIs to prevent the new page from loading?

    I get that “ok=true” page as well. Is there any way to get rid of that?

    There is a way to get rid of that ‘ok=true’ but that will require posting the form in background, using ajax.

    In order to do a cross-domain http request, a ajax proxy is needed. Can even use flash if you want everything running on the browser (check FlashXMLHttpRequest).

    Since it’s such a high demand, I will try to write a short article this days and give a complete example on that.

    Is there a way to have the widget call a pre-programmed number without having the person clicking on it type in a number to call ? Thanks.

    This worked flawlessly! Another great tool for removing Flash from our sites. Not to mention the awesome ability to fully customize/design the input to work with my client’s brand.

    I have a question about google voice installation problem. My cell is TRACKPHONE. I completed the installation process just fine until I was waiting for the phone to ring to input my code. My phone never rang. I tried many times. Am I doing something wrong or is TRACKPHONE not able to be set up on google voice? I know this is a bit atypical from your usual questions, but it is important to me to ask. Thanks.

    Well i think they changed the widget. The very first instruction you give is to grab the id within the flashvars param. Well there is no longer an ID in that param.

    Now what?

    Please ignore my previous post, and reply to this instead:
    Can you explain how to post the form with ajax?

  25. TC said:

    If this script were coded with Ajax instead of Java Script could I hide the Google Call Widget ID the way that PHP hides the destination e-mail address in a form mailer?

    I am using this on my personal blog, and it seems to have stopped working. I no longer get the “Call Sent” dialog box. Any ideas? I’m just starting to diagnose. Thanks, it’s a good tool you’ve given us.

    Your widget looks great. It styles using my WP Theme styles. It fits the widget box perfectly.

    When I try to use it, I get directly to this page:

    with the message


    Any suggestions?
