What is SIP Trunking?
SIP (Session Initiation Protocol) trunking is a telecommunications technique made possible with VoIP (Voice Over Internet Protocol) phone systems. SIP trunking provides a virtual connection over the internet, unlike traditional phone systems, which are physically connected to a phone company through landline telephone lines. Although multiple lines are shared, call volume is increased and each user can still have a direct inward dialing (DID) line. Also, DID lines are less expensive when purchased with a SIP Trunk.
Three Benefits of SIP Trunking
SIP trunking provides a flexible, cost-effective and reliable solution to suit your communication needs. Among this technique’s many advantages are:
- Scalability. Standard PRIs are sold in groups of 23 channels, but SIP trunks are sold individually on an as-needed basis. As your business grows, simply add more channels. Additionally, a business can buy more DID numbers than SIP trunks. This provides a low-cost way for a business to allocate private incoming numbers to each employee without having to pay for a dedicated line or SIP trunk for each.
- Affordability. Calls made through SIP trunking travel primarily over the internet and not through landline telephone lines, which substantially reduces or eliminates long-distance charges.
- Reliability. In the event of a power outage, SIP calls can automatically be re-routed to an alternate office location or mobile devices. Also, a company can elect to have redundant internet services at their place of business enabling SIP trunks to have multiple pathways limiting costly downtime.
