With the advent of VoIP and computer telephony integration, one feature that have popped up is Click2Call. Its a convenient way to initiate a call with people whom you want to talk to by just clicking on their number in Outlook or on some webpage etc etc.
Vonage has this feature for their service.
Lets see how we can achieve this with Asterisk. Asterisk provides Originate AMI action for this. Just call the Originate action with the numbers you want to connect. Here is the
twisted code on how you can do it ( You need
starpy to do it). The following dirty example integrates http with AMI where by hitting the url some thing like http://localhost:8000?number=12322342345&ext=234 will do the magic needed. The same way you integrate this with any other protocol you think that it useful to you. After all twisted supports tons of those.
