Location Mobility

Move across the country overnight without contacting your service provider to let them know.  SIP Trunking offers true maneuverability no matter where your business calls you to go.

Cell Phone Support

Requirements are no longer limited to wired systems. Organizations can now leverage voice over cellular while enjoying the feature set of a corporate PBX.

Virtual DID's

Organizations can have DID's nationwide or local regardless of their location. Virtual Conference Center: Unlimited number of conference calls that can be routed by DID or Auto Attendant.

Trunk Consolidation

In a multi-site environment, SIP Trunking lets you eliminate individual telephone circuits (traditional phone lines) at each location, consolidating all locations into one centralized site.  This results in reduced hardware and significant cost savings over time.

Remote Workers

Normally, companies that have premise-based PBX's have little to no features they can offer to their remote employees. Just a few dollars is all it takes to launch your business into the 21st century with SIP Trunking, which allows your systems to remain accessible to even your most remote team members.

Dynamic Line Bursting

Nothing turns an interested consumer away quite as effectively as getting a busy signal.  Dynamic Line Bursting ensures that even during peak hours, your customers never receive a busy signal. Never risk not having enough call paths or phone lines again as SIP Trunking allows your customers to "burst" over the total number of your prepaid call paths.


SIP Trunking offers you the opportunity to grow your telephony network the way your business needs by eliminating the need for over-engineering of your phone systems.  Say goodbye to purchasing more phone circuits than you really need and instead, take advantage of SIP Trunking's single-increment scalability.

Disaster Recovery

Designed to protect business customers by increasing reliability and survivability during unexpected service interruptions, SIP Trunking disaster recovery provides continuity of service by systematically re-routing incoming calls to cell phones, voice mail boxes or branch offices.


Understanding SIP Trunking

Using your IP-PBX system as a foundation, SIP Trunking unifies your communications, giving you the ability to send multiple types of data over one line.  Experience the benefits of utilizing data, voice and internet over your IP connection, increasing productivity, reducing overall costs and improving your network capacity.

Differences:One of the main differences between these two services is size of intended use. For example, for a small business with 20 employees or less, Hosted PBX solution is the better choice. Opposite this, businesses with 20+ employees typically benefit from SIP Trunking service. While both services offer the same services, Hosted PBX offers a less expensive smaller scale, which can better benefit small businesses.

Another difference rests within the level of flexibility both services offer. Typically, SIP Trunking provides the same IT infrastructure to maintain a user’s PBX, but also offers a greater level of flexibility in pricing. In using SIP Trunking, users can employ multiple service providers based on rates and time of day. Opposite this is the Hosted PBX service. The Hosted service can potentially cut some configuration; however, many providers are willing to meet users’ requirements.

SIP Trunking is also able to offer superior security. Hosted PBX leaves ports open, which defeats the purpose of a firewall and leaves your system open to serious security issues. Additionally, the IP PBX that is utilized by SIP Trunking allows for much less bandwidth to be used. Hosted PBX on the other hand uses as much as 6-8 times more. This is due to Hosted PBX’s inability to scale accordingly.

Both SIP Trunking and Hosted PBX services offer a number of features and benefits. While they often overlap, SIP Trunking is becoming the more commonly selected option. This is a result of a number of advantagesincluding increased security, quality of service, greater cost efficiency, and flexibility. Despite this, Hosted PBX services still offer users tremendous features; however, they ultimately are not as inclusive as the SIP Trunking service.

SIP Trunking: SIP (Session Initiation Protocol) Trunking enhances the quality, reliability, efficiency, and greater cost efficiency of a company's communications by eliminating the need for Primary Rate Interfaces (PRIs), ISDN Basic Rate Interfaces (BRIs), and local Public Switched Telephone Network gateways. Ultimately, SIP Trunking uses VoIP to facilitate the connection of a PBX to the internet. In order to utilize SIP Trunking, users must have a PBX capable of connecting to all internal end users, an Internet Telephony Service Provider (ITSP), and a gateway that works as an interface between the PBX and ITSP.

With SIP Trunking, the internet replaces the traditional trunk (a line/link that carries multiple signals at once, connecting centers and nodes in a communications system). In doing this, users are able to communicate with both fixed and mobile subscribers all over the world.

While SIP Trunking includes the same set of standard of VoIP features, (similar to a Hosted PBX), this service also allows for data to be combined, voice and video in a single line. Subsequently, this eliminates the need for separate media for each mode. As a result of this, users experience greater cost efficiency and reliability.

Hosted PBX: Hosted PBX is a telephone system that provides advanced VoIP services while not having to account for all the necessary on-site equipment. PBX (Private Branch Exchange) is where an incoming call can be routed to different extensions; therefore, when the PBX is hosted, the user does not have to provide as much on-premises equipment, (someone does need to provide the telephones, etc). The service provider handles the technical aspect(s), insofar, as the contract allows.

Notwithstanding, the technical aspects and benefits that Hosted PBXs offer, which are actually the exact same as On-Premise PBXs. In addition to routing calls, handling holds and transfers, and allowing more than one person to be reached from a single business number, Hosted PBX also manages all incoming calls (not immediately picked up). Hosted PBX also comes full with standard VoIP services including voicemail, faxes, automated greetings/messages, touchtone menus, conferences, call records, and phone calls.

While SIP Trunking comes equipped with the above features, Hosted PBX also offers cost efficiency as there is no high startup cost for buying hardware. Also, there’s never upgrade cost or changing hardware costs. Hosted PBX allows small businesses to receive PBX service easily.

VoIP services involve phone calls being made over the internet, as opposed to traditional "P.O.T.S." (Plain Old Telephone Service) landline phone calls being made over the traditional "PTSN" (Public Switched Telephone Network) In doing so, VoIP offers services that include tremendous cost efficiency as well as advanced features. Among these advantages are VoIP services on Hosted PBX services and SIP Trunking services. While these services are similar in function and feature, they also represent different means to the same end. With that, it may be hard to differentiate the services. While each service has various applications, both often overlap one another. For example, SIP Trunking services require an IP-PBX.
