Free gateways from Skype to SIP and back
In the process of working on one project, it was necessary to organize a conference call between people located in different time zones. At the same time, the project is still non-commercial, respectively, access should be free.
At that time I already had a working server with FreeSWITCH, used as a mini-PBX for one subscriber.

Almost every participant already had Skype, i.e. Ideally, it is necessary that people can get from Skype to my frisvich. Well, the most advanced could launch the SIP client.
To date, several free gateways for calls from Skype have been found:
There are also several possibilities for calls from SIP to Skype:
Also FreeSWITCH is able to automatically turn on the conference recording as soon as there is more than one participant in it. It helps a lot if people are in different parts of the world and always someone can not join - he has the opportunity to listen to the recording later.

To date, several free gateways for calls from Skype have been found:
- Skype: bgopen - provided by the Bulgarian provider bgopen.net. After the call, you can dial any extension from sipbroker.com. Some complain that calls are sometimes broken.
- skype: skype.sipnet.ru - the entry point of the Russian provider SIPNET. After the call, you can dial the number of the subscriber. If the frisvich has one of the gateways registered on the sipnet, we receive an incoming call to the frisvich.
- Perhaps the most interesting option: the Tropo.com service provides free access in developer mode. Each application receives a unique number to which you can call from Skype for free (numbers from a drawn country code +990, so Skype does not take anything for them). Accordingly, if you make an application consisting of a single transfer () call to our SIP URI, we get a free gateway that sends calls to our station. The only small inconvenience is that their server is in America, so there is a noticeable voice delay.
There are also several possibilities for calls from SIP to Skype:
- The Comfytel.com service allows you to forward incoming SIP calls to your registered Skype account.
- The service Zadarma.com recently introduced the service of calls to Skype, and you can call to any Skype account
Also FreeSWITCH is able to automatically turn on the conference recording as soon as there is more than one participant in it. It helps a lot if people are in different parts of the world and always someone can not join - he has the opportunity to listen to the recording later.
