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.

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.

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.

No, a Quality of Service (QoS) router is not necessary to deploy SIP trunking service.

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.

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

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.

Disaster Recovery provides automatic failover capabilities so you'll never lose a call during a system failure, power outage or internet outage.

SIP Trunking channels are digital phone lines that provide calling services to businesses with on-premise office phone systems.  SIP Trunks replace traditional landline service.

A Cloud PBX incorporates SIP calling services within its software so all calling services, features and applications are in the cloud.
