For telephone calls through the SIP protocol, TekSIP, a registered and stateless SIP proxy, has been created specifically designed for Windows operating systems. For each SIP point, TekSIP informs us of its IP address, the port, the corresponding date and time, at which the communication has been established.
The SIP protocol is one that uses IP communications, in which neither audio nor video is transmitted, only data, the transmission of which is done through the 5060 TCP or UDP port and which, therefore, are more difficult to control. For this reason, TekSIP has been created.
TekSIP is a completely free tool that takes up very little space on your hard drive: less than half a megabyte. It works on Windows XP and Vista operating systems. Its creators allow you to use it with total freedom for both personal and commercial use. The only thing they ask for in return is to inform them of the incidents that occur during their use (feedback), in this way they will obtain the necessary information to repair the application and solve possible problems.
If you usually make data transfers through the SIP protocol, do not miss the opportunity to download and install, completely free, this fantastic application, called: TekSIP.
You can free download TekSIP 32, 64 bit and safe install the latest trial or new full version for Windows 10 from the official site.
