What Makes Our SIP Trunking Services Different

dSIP Trunks are burstable, a unique feature which provides additional channels to accomodate higher than usual call volumes. This increases your call completion rates and ensures your callers never get a busy signal.

Our new dSIP trunking solution allows any compatible IP based PBX or even traditional telephone equipment to use your existing broadband connection to deliver phone numbers and dial tone.

dVoice allows you to converge all your voice and data between your office and the PSTN (public switched telephone network). SIP trunking solutions from SimpleSignal deliver productivity-enhancing, money-saving IP telephony features, while using your existing PBX equipment.

The Primary Benefit of SIP Trunking

Traditional business phone systems are powered by PRI's which include 23 channels. No more, no less, and you must purhcase all 23 channels at a time. SIP trunks can be purchased one at a time, allowing your business to scale as demand dictates. The dramatic cost savings, coupled with voice quality and reliability that equals or even surpasses traditional phone providers is making SIP trunks the logical choice.

What is a Business SIP Trunk?

Simply put, a SIP Trunk is a single voice call routed over your Internet connection. dSIP uses your Internet connection to bring voice services of tomorrow to your clients today. Trunks are purchased according to the number of anticipated simultaneous calls in an enterprise. If you find you need more call capacity, you can simply add trunks as needed. dSIP is your conduit to the converged IP world.

Built-in Disaster Recovery

You'll never miss a call with our "No Fear" failover system. If your trunk is damaged, your call can automatically be re-directed by dVoice's switch to your cell phone or alternate landline.

How SIP Trunks Work with dVoice

dVoice blends connections for both data and voice into a single line. By serving as a converter between a legacy phone system and a company's Internet connection, a SIP-trunking device allows the data network to carry voice traffic. Features typically include local and long-distance calling, E911, directory listing and caller ID, all of which integrate into a company's existing phone system.

SIP trunking consists of three primary components. These include:

IP PBX

An IP-based PBX communicates with all endpoints over an IP network. It also switches calls between VoIP users on local lines while allowing all users to share a number of external phone lines. The typical IP PBX can additionally switch calls between a VoIP user and a traditional-telephone user, or between two traditional-telephone users in the same way that a conventional PBX does.

Our Role

The role of SimpleSignal is to ensure connectivity to the PSTN from an IP network for mobile and fixed communication devices. It also transports IP communications across a private IP network or public Internet.

The IAD (Internet Access Device)

This device facilitates connectivity between an enterprise IP network, the PSTN and SimpleSignal's network.

Note that dVoice will typically include SIP trunking as an element of an IP-phone-system package. It will only be separated into hybrid solutions when there is a need to maintain some locations on a traditional TDM (time-division multiplexing) system, which will connect to the overall IP infrastructure through various border elements and a SIP trunking service.
