Click to Call for Google Chrome™
Click on any phone number on any web page and your phone dials the number!
What is it?
The Click To Call (C2C) plugin is an add-on for Chrome that allows you to click to call phone numbers or SIP addresses within your browser. This plugin will also notify you of incoming calls with real-time pop-ups containing caller-ID information.
How does it work?
Outbound click to call
- See phone number.
- Click phone number.
- RRRRING!
This Chrome add-on locates telephone numbers in web pages and converts them to Click-to-Call links on the fly.
When you roll over a phone number with your mouse, you will see the number change to a link similar to this:
When you click on one of these links, a call is placed to your OnSIP SIP address. When you answer, the call is patched through to the telephone number.
You need an OnSIP account to use this Chrome add-on and standard calling rates will apply.
Inbound calls: browser notifications
- You are at your computer, browsing the web with Chrome
- Caller dials your phone number
- Your phone rings, and you see a browser pop-up with Caller ID
When you are viewing Chrome and receive a call to your OnSIP extension, a browser pop-up like the following will appear:
If you are a Highrise user and have identified this number belonging to a customer, a browser pop-up like the following will appear:
Installation
To download and configure the C2C plugin for Chrome:

- Download the C2C plugin file here at the Chrome web store
- Open C2C plugin and confirm installation. The C2C plugin is now installed in your browser.
- To configure in Chrome, select Window > Extensions > Options.
- On the top right, enter your SIP address and password: the same set that you use to login to my.onsip.com. In case you're new to my.onsip.com, visit this page to find out how to get your password.
- Click Save to take advantage of the click-to-call functionality.
- Immediately after clicking save, click Allow to take advantage of Caller ID browser pop-ups. (You can turn these off in the future if you wish.) If you missed the option to Allow pop-ups, click "Save" on your settings again, and it will appear.
Additional Functionality
Highrise
Highrise is a powerful customer and contact relationship tool on the web. Using Highrise, you can keep track of every customer interaction – from emails to documents and contact information.
Now, OnSIP has made it even easier to log phone calls with customers in Highrise with the OnSIP Click-To-Call (C2C) plugin for Chrome.
If you are a Highrise user, you can also take advantage of further features:
- Real-time notifications when Highrise contacts are calling; the C2C plugin will recognize when a Highrise contact is calling you and will display the contact in the pop-up.
- Each time you converse with a customer, the C2C plugin will insert a note in Highrise so you can keep track of your communications.
Setting up Highrise Integration
- If you have a Highrise account, go back to the Options menu. (In Chrome, select Window > Extensions > Options)
- Enter your Highrise domain and API Key in the appropriate fields. Note: If you have any questions about either of these fields, simply hover over the question mark for a tip.
- Select your timezone from the dropdown.
- Once you have entered the appropriate fields, click Save.

Troubleshooting
I am not seeing pop-up notifications when I make or receive a call
To receive pop-up notifications:
- Ensure you have enabled pop-up notifications. Chrome > Preferences > Under the Hood > Content Settings > Notifications > Choose "Allow sites to use desktop notifications" or "Ask me when a site wants to show Desktop notifications."
- If you have clicked, "Ask me when a site wants to show Desktop notifications," ensure you have clicked to Allow OnSIP C2C Extension notifications. Go to Window > Extensions > OnSIP C2C Options > Click to Save settings again. Immediately at the top, you will see a yellow bar that prompts you for permission to allow notifications. Click Allow.
I don't want to receive Caller-ID browser pop-up notifications.
To stop notifications:
- In your browser, click Chrome > Preferences > Under the Hood > Content Settings > Notifications > Choose: "Ask me when a site wants to show Desktop notifications."
- In the same window, click Exceptions. Click to Remove the OnSIP C2C plugin.
- If you make modifications to the OnSIP C2C plugin, be sure to click Deny when the plugin prompts for pop-up permission.
"OnSIP credentials are invalid" shows when I save my settings.
Be sure you are using the same SIP address and password you use to login to my.onsip.com. If you do not remember your SIP address and password, visit my.onsip.com and click "Send password." Or, see your OnSIP Account Administrator.
If you are hosting your own domain you *must* put in an XMPP SRV record for both xmpp-client and xmpp-server:
_xmpp-client._tcp.junctionnetworks.com. 300 IN SRV 0 0 5222 xmpp-client.onsip.com._xmpp-server._tcp.junctionnetworks.com. 300 IN SRV 0 0 5269 xmpp-server.onsip.com.

Clicking isn't triggering a call.
Suddenly, no matter which site I am using, the C2C plug-in doesn't trigger a call when I click on a number. Phone numbers still become hyper-links however clicking does nothing. I'm using Bria for Mac as my softphone and the two have worked seamlessly for months now.
Troubleshooting thus far:
- Turning C2C off and on.
- Re-entering C2C credentials (and the Highrise credentials)
- Removing and installing C2C plugin from scratch.
- Quitting Chrome, Bria, and restarting my Mac and opening the applications in different orders. I've tried all sorts of sequences and that doesn't seem to help.
Yesterday I was able to use C2C once (out of nowhere), but for the rest of the day it continued to not work.
I'm using Bria 3.1 and Mac OS X 10.6.8. This was happening in 10.6.7 as well.
Thank you!
Please submit a support ticket
Please log into the admin portal and choose "Contact Support" to submit a support ticket for this issue. It looks like you've gone through all the normal troubleshooting attempts.
Make sure, however, that you can receive calls normally. A click-to-call starts out as just an inbound call to your phone. If you are having network issues that are preventing inbound calls in general, then C2C will not work either.
