Service of direct SIP calls call2sip.ru
Last week, we talked about direct SIP calls. But as they say, an article to write is not a Facebook to create, so we present to your attention a web service of direct SIP calls.

The service allows you to make calls to any SIP addresses, as well as receive calls directly to the browser.
- You can specify a link to contact you in a letter,
Example: http://call2sip.ru/#info@onlinepbx.ru . The address after the hash will be specified in <input />.
- For quick voice communication between two computers with a headset.
Each person who visits the site is randomly given a SIP address (displayed in the lower right corner). Send it to the interlocutor in the above way.
- As a button "call from the site" (thanks to the responsive design).

By the way, in my opinion, this is the first service for calls from the site with the ability to call back.
- As an application for SIP links sip: info@onlinepbx.ru (does not work here, Habr adds http: //)

Well, firstly, for our beloved customers, whom we often pamper.
Secondly,so that the Asteriskers chopped a chip to popularize direct SIP calls.
Thirdly, it is necessary to constantly pump our skill and level.
Installed Freeswitch , screwed rtmp_mod , wrote a couple of scripts in Lua . And further: Apache, MySQL, PHP and all kinds of front end there. The topic of freeswitch is quite extensive, advise what to write about.
PS To check the performance of your microphone, call echo@call2sip.ru
UPD Apparently, we broke the record for the number of received direct SIP calls to info@onlinepbx.ru. In two days, ~ 300 calls, most simply hang up, many say that they check the quality of communication, some are interested in our service. In total, over 3,500 calls were made in two days. About 20% of calls to third-party servers were successful.
Well, a fly in the ointment: - many did not start flash.
