BUSINESS-CLASS VOIP PHONE SERVICE

SIP Trunks are virtual, “cloud-based” high definition (HD) phone lines that utilize a Broadband connection and your business phone system for access. Session Initiation Protocol (SIP) has become the common signaling standard for real-time business communications for Voice over Internet Protocol (VoIP).  As a SIP Trunk provider, SIP allows us to packetize and prioritize multimedia traffic over digital circuits, offering higher quality and more reliability than traditional VoIP phone service.
SIP Trunking enables you to eliminate the cost of maintaining two networks (POTS + Ethernet) by placing your phone traffic on your Ethernet network. Additionally, SIP Trunks allow two devices to have several different methods of communication streams running, allowing businesses to transmit several voice paths over one channel. This allows for everyone to receive a personal business phone number, but only one phone line is needed.

 


HOW DOES IT WORK?

Working with our upstream Carriers, ACC Telecom provides SIP Trunking service to existing, on-premise business phone systems and remote employees by utilizing broadband connections. Though SIP is a signaling protocol used within the Voice over IP umbrella, it is inherently faster, more adaptable and scalable than traditional VoIP services.
SIP Trunks can carry all forms of media, such as voice, video, and data and can handle large amounts of data and traffic while adapting its signaling protocol to match that of the PBX system. For these reasons, SIP Trunks are preferred by companies that have multiple branches or remote workers or implement a video calling and video conferencing solution.

FAQs

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, 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 tend to employ SIP services over landline service because of its networking capabilities.  Based on these facts, companies tend to report a 40%-75% 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 too.  

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 and Hybrid phone systems are the best PBX systems to deploy a SIP Trunking solution.   Antiquated digital 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
  • 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 reports 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. 

What are Burstable Call Paths?

First off, think of 'call paths' as phone lines.  As an example, let's say your company has 10 call paths.  If all 10 call paths are in use and you receive an 11th inbound call- normally that 11th caller would receive a busy signal.  With our Burstable Call Path feature, your call paths 'burst' by adding an additional, temporary call path so that 11th caller can get through to voicemail or Auto Attendant- rather than hearing a busy signal.

How Does SIP Trunking Differ From a Cloud PBX?

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.
