arrow WHAT IS SIP TRUNKING
SIP trunk simply stands for Session Initiation Protocol that is a service offered by an ITSP (Internet Telephony Service Provider) in conjunction with a PBX/IP-PBX or as replacements for traditional PRI, PSTN (analog circuits) but can maintain the same and even more advanced features of what the traditional circuit does. Eliminating the need to subscribe expensive PRI/analog traditional lines while allowing the user to buy just the capacity they need.

A SIP trunk is a service offered by an ITSP (Internet Telephony Service Provider) that permits businesses that have a PBX installed to use Voice-over-IP (VoIP) also outside the enterprise network by using the same connection as the Internet connection.

SIP trunks can offer significant cost-savings for enterprises, eliminating the need for local PSTN gateways, costly ISDN BRIs (Basic Rate Interfaces) or PRIs (Primary Rate Interfaces).

There are three components necessary to successfully deploy SIP trunks: a PBX with a SIP-enabled trunk side(IP PBX)or an enterprise SIP Device with PBX and an Internet telephony or SIP trunking service provider.

arrow WHAT YOU NEED TO KNOW BEFORE GO FOR SIP TRUNK?
Moving to SIP Trunk telephony may require more than just a new IP-PBX. Be sure you are getting the right points to avoid unexpected surprises; you need to know how much more before you go for it. Some questions may be greatly helpful to know how to pin down your costs include:

  First, get to know how many simultaneous calls you usually received as per your daily operation, what size for business and that to check the required bandwidth you may need. You know when a SIP Trunk is not fully being used; its unused bandwidth is free-up for use in less intensive applications, such as e-mail and other on-line activities. This dynamic allocation of bandwidth is highlighted as an advance feature of SIP Trunks that traditional analog or PRI technologies doesn’t has at all.

Second, clarify if the existing IP-PBX/PBX is SIP-enabled model which is compatible to work with SIP Trunk or purchase new equipment. Whether use your existing phones, coupled with some way to combine your existing phones or need a new IP phones.

Third, compare see if your Potential Provider is able to provide any add-on services and features like T.38 Faxing support, provision of DID, VOIP solution etc. That’s what TieUs All-in-One Stop concept works for.

arrow HOW CAN SIP TRUNK VOIP HELP BUSINESS
SIP Trunk VoIP can be deployed from companies existing PBX system directly if it is IP enabled. If not, a gateway is installed that converts the traditional POTS line to VoIP. SIP Trunk VoIP is best suite for small businesses that want to deploy telephony phone service while utilizing their existing PBX phone system. If PBX is not IP enabled a gateway is installed on the premise on the PBX and converts all calls from traditional phone service to VoIP. This type of VoIP service can drastically decrease company phone bills up to 60%.
 
arrow KNOWLEDGE OF SIP CONNECTION
A SIP (Session Initiation Protocol) connection is a service offered by many ITSP (Internet Telephony Service Providers) that connects a company's PBX to the existing telephone system infrastructure(PSTN) via Internet using the SIP VoIP standard.

Using a SIP connection may simplify administration for the organization 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 standard TDM PSTN connection.

Thanks to the SIP protocol, transmitting Caller ID and other call-related information is easy and even other information 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.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.
