TekSIP allows you to identify the incoming IP addresses that are attempting to connect with your computer when using a VOIP software to make phone calls over the internet. It supports RFC platforms and ENUM domains. It allows you to keep a record of the messages you receive from your system and the information about the sessions or phone calls you have performed during a determinate amount of time. Also, it enables you to send incoming calls to endpoints and put them on hold or tell the caller you are busy or offline. In addition to that, it lets you monitor real time calls and listen to the conversation.
