This is a simple SIP (VOIP) outgoing telephone based on C#. This SIP application has been developed and is currently using Help - > Call Support. The idea is to create a zero-configuration, very simple outgoing phone, which is what it is now (although it supports IP-based incoming calls; for example, sip: test @ ip: 7666, 7666 is port SIP_Callout running).
