Business VOIP Phone Service
As such, SIP Trunks allow for everyone to receive a personal business phone number, but only one phone line is needed. As such, SIP service is typically more cost-effective and scalable than traditional phone service alternatives. And with our geo-redundant platform and failover features, you can rest assured that your business lines will always be accessible.
What Are SIP Trunks?
Additionally, SIP Trunks allow two devices to have several different methods of communication streams running, allowing businesses to transmit several calling paths over one channel. SIP allows businesses to network all of their locations under one account, so for example, an inbound call can ring to multiple locations.
How Does It Work?

How will SIP trunking benefit my business?
SIP Trunks offer significant advantages over landline phone service, notably the flexibility and price. Analog lines have limited functionality and high costs. SIP Trunks, however, are quality reliable, less expensive, and offer network solutions. Today, with SIP technology, choices are much more dynamic and offer a host of solutions and features tailored to each individual company.

How does SIP Trunking differ from traditional phone lines?
Using your companies existing bandwidth, Session Initiation Protocol (SIP) trunks provide a digital version of a phone line by removing the need for physical assets such as wiring and boxes. In addition to this wireless connectivity, SIP Trunks are much more versatile than traditional phone lines, allowing for the transmission of voice messages, data, and video. Furthermore, companies with multiple offices and remote employees choose SIP trunks because of its networking capabilities. Based on these facts, companies tend to report a 40%-60% savings when switching from traditional phone service to SIP Trunking service.
What are the differences between VoIP and SIP?
Voice over Internet Protocol (VoIP) and Session Initiation Protocol (SIP) may act similar from the outside, but they operate differently. One of the main differences between the two is their scale. VoIP enables inbound and outbound calls dedicated to one particular outlet, whereas SIP is a much larger application that has the ability to spread transmissions to many users at once- sending not only voice messages but data and video as well.
Do SIP Trunks use a lot of bandwidth?
SIP Trunks do not use a lot of bandwidth- only 88KB per call. In comparison, sending an email with a 1-page PDF attachment uses around 180KB.
Do I need a QoS router to use SIP Trunks?
No, a Quality of Service (QoS) router is not necessary to deploy SIP trunking service.
What types of phone systems are compatible with SIP Trunks?
IP, Hybrid, and some digital phone systems are the best PBX systems to deploy a SIP Trunking solution. We recommend our 3CX IP Phone System because 3CX does not charge per-user licensing, application, or extension fees.
Antiquated phone systems are capable of implementing SIP service by adding a gateway, however, it is not recommended due to reported call quality issues.
What is multi-office networking?
Multi-office networking refers to a company with multiple office locations- including remote workers- that share phone service and PBX features and applications. Normally, one location will house the on-site IP business phone system while the remaining locations connect to the main hub using IP phones. This enables employees to extension dial, intercom, and seamlessly transfer calls back and forth to various office locations. Companies that network their locations with SIP Trunks save time and money by:
- Reducing the number of personnel answering the phones
- Reducing the number of phone lines and phone numbers needed
- Combining phone service and eliminating long distance charges
- Receiving & processing only one invoice for all locations
What is Call Accounting?
Call Accounting provides call details on inbound, outbound, and internal calls. Our complimentary Call Accounting reporting examples include graphs on call activity, and concurrent call usage.
What is Disaster Recovery?
Disaster Recovery provides automatic failover capabilities so you’ll never lose a call during a system failure, power outage or internet outage.
How does SIP Trunking differ from a cloud PBX?
A Cloud PBX incorporates SIP calling services within its software so all calling services, features and applications are in the cloud.
