SIP Softswitch
It is a device capturing and controling all the signals, which are being created by the whole system, especially the made and received phone call signals. The device is mostly used for connecting regular phone system with the Internet and backwards.
The function of the return call allows you to quickly and comfortably connect to the person, who has called you as the last. Simply dial *69 (USA) in order to find out the number and the call time, after that press the “1” key to make the call. In case the number is busy, the system will try to reach the line during 30 minutes and when the person will be available, you will receive a signal and be connected.
