"SIP Termination and Origination. We Can Provide SIP Termination For You Anywhere In The World...

A SIP connection is a service offered by an ITSP (Internet Telephony Service Provider) that connects a company's PBX to the ordinary telephone system (PSTN) via Internet using the SIP VoIP standard.

Using a SIP connection may simplify administration for the organisation as the SIP connection typically will use the same Internet connection that is used for normal data. This eliminates installation and maintenance of a BRI/PRI connection at each location. However, this almost always comes at the expense of the reliability of a real TDM PSTN connection.

Thanks to the SIP protocol, transmitting Caller ID and other call-related information is easy and even other information like pictures of the caller can be transmitted. Because SIP connections are digital, the voice is also transmitted digitally and can have excellent audio quality and issues from analog lines like connect and disconnect detection are simple.

Also, there is no need to limit the telephone number to 10 digits. This makes it possible to assign Direct Inward Dialing numbers for every extension, so that the auto attendant in the PBX plays a less important role.
