Budget sip trunk providers.
Voice over internet protocol or voip is a rapidly developing area of technology. VOIP can be implemented in a software as a soft phone using VOIP phones or by adapting an existing telephone using an analog telephone adapter (ATA) to connect it to an IP network. VOIP uses a special set of protocols to send and manage communications. Session protocols include session initiation protocols (SIP) and skinny call control protocol (SCCP) and packets are often in real time transport protocol(RTC) format. The problems with firewall and NAT (network address translation) traversal are describe as well as how Simple Transversal of User Datagram Protocol(STUN) solves them in some instances. The primary motivation for using a VOIP has historically been the greatly reduced charges imposed for long distance connections. The primary draw back has been that VOIP consolidates your telephone and internet into one line and if your internet connection is broken, you loose both methods of communications. Early implementations of VOIP suffered from voice quality problems but the current technology delivers voice quality that is as good as and often better than telephone lines.
