What is SIP Trunking?
SIP (Session Initiation Protocol) Trunking refers to the use of VoIP (Voice Over Internet Protocol) to connect your premise-based phone system to the Internet. A broadband or Internet connection replaces traditional, plain-old-telephone POTs or Primary Rate Interface (PRI) lines, allowing your organization to communicate more efficiently with better scalability.
SIP Trunking may be utilized with virtually any PBX system, including modern IP based phone systems or older-styled analog systems. The older systems may require an integrated access device (IAD) to bridge the SIP connection to your PBX. However, SIP Trunking will bridge your company to the modern communications cloud, helping connect all office and mobile users together.
Types of SIP Trunking
Standard – A standard SIP trunk delivers calls to the premise equipment and acts like a CO line. If the SIP endpoint is offline or cannot be contacted by the system, the system issues busy signals to the incoming callers.
Enhanced – An enhanced SIP trunk delivers calls to the premise equipment and acts like a CO line. If the SIP endpoint is offline or cannot be contacted by the system, the system provides an alternate route for incoming calls, which acts as a powerful and flexible disaster recovery feature. Alternate routes include routing calls to an auto attendant, other SIP trunks (at other locations), voicemail, or a Find-Me Follow-Me sequence.
