The latest Telguard development is a whole new system, future proofing for both installers and end users. The new standard based SIP interface will support connectivity to large customers PBX systems over IP or for smaller / residential connection to the Telguard host. This will remove the need for an analogue phone line or a GSM SIM card providing that a suitable IP connection is available.  

We will also be incorporating a simplified implementation process which we expect to significantly reduce installation time compared to existing IP based systems. With the prospect of a Web based admin tool we fully expect this new product to be ground breaking!

SIP is the Session Initiation Protocol.  In IP and traditional telephony, network engineers have always made a clear distinction between two different phases of a voice call.  The first phase is "call setup," and includes all of the details needed to get two telephones talking.  Once the call has been setup, the phones enter a "data transfer" phase of the call using an entirely different family of protocols to actually move the voice packets between the two phones.  In the world of VoIP, SIP is a call setup protocol that operates at the application layer.  You may have also heard of H.323, an ITU protocol with similar function.

SIP is a very flexible protocol that has great depth.  It was designed to be a general-purpose way to set up real-time multimedia sessions between groups of participants.   For example, in addition to simple telephone calls, SIP can also be used to set up video and audio multicast meetings, or instant messaging conferences.  In this document, we'll focus on SIP's capabilities for VoIP, and how it sets up calls that then use RTP (the Real-time Transport Protocol) to actually send the voice data between phones.
