What is SIP Trunking all about?
SIP; which stands for Session Initiation Protocol is a communications signalling methodology that can control voice and multimedia communications in an enterprise. SIP Trunking allows calls to be routed over the IP backbone through VoIP (Voice over IP) technology. They are used altogether with a reliable IP-PBX system and are considered to be more advanced alternatives for traditional analogue circuits and PRIs. The features of SIP trunk allow low cost, scalable, feature-rich and flexible business communications.
What are the advantages of SIP Trunks over analogue circuits or PRIs?
SIP Trunks offer more cost savings to companies whilst enhancing quality of business services. Moreover, with SIP, international calls are routed over the IP which means they cost just like local calls. Unlike PRIs, SIP trunks are scalable which means they can handle as much calls as the bandwidth permits without needing additional hardware to support such traffic.
Since SIP Trunks makes use of Internet connectivity, how fast should be broadband service be?
With as low as only 384Kbps, SIP trunking can already work in a small-scale system that can handle two calls at the same time. If additional calls are needed, additional bandwidth may be necessary. You can ask your SIP provider to give you the exact bandwidth you need depending on your business needs.
What equipment do I invest in to use SIP Trunking?
SIP Trunks are designed to be compatible with any SIP-ready PBX system. SIP Trunks can integrate fully into a business? existing telephone system. It can work with traditional key systems with IAD (Integrated Access Device) or analogue circuits. Depending on the type of telephone system you already have, you may or may not need additional hardware.
Should my business choose SIP trunking instead of a hosted system?
Whether SIP trunking is ideal for your business would depend on your needs. You should consider SIP Trunking if you think your communications system is best with a premise based system (IP-PBX) or if you already have one existing. If IP-PBX is coupled with SIP, your business communications can enjoy features much like that of a hosted system. However,
SIP Trunks can save you much more as SIP Trunks can service three or four calls simultaneously (depending on your connectivity and your subscription), while a hosted system can only account for one.
Is SIP Trunking only applicable for voice calls?
No, it is not limited to voice services alone. SIP Trunking also allows other channels of communication including video or voice conferencing, instant messaging, live meeting web conference, toll free calling, E911, and directory services.
Should I need more bandwidth in order to buy SIP Trunks?
As mentioned earlier, you may need to increase your Internet bandwidth with SIP Trunks. However, note that one of the features of SIP Trunking is dynamic bandwidth allocation. This means that when your SIP Trunk is not being used, the bandwidth can be freed for use in other applications.
