Our Voice Solutions


Technology advances are accelerating the integration of the communications and IT worlds into a cohesive, inseparable business catalyst. With so many options, the method by which busy executives strategize, source, implement, and maintain their carrier services is more important than ever before. The telecommunications landscape can be confusing, time consuming and unnecessarily expensive for IT managers who don’t speak the language or fully understand the landscape. Connectivity, compliance, security, uptimes and service levels are just a few variables to manage, and each metric varies from carrier to carrier and from company to company. Through our strategic relationships with 50+ carriers and suppliers, OnCall Telecom is your strategic partner that will help your IT department navigate through the noise, ensuring that your carrier services integrate powerfully with your IT infrastructure and business vision. And we’ll be your single point of contact for all carrier service related issues for your business for the lifetime of your contract.

Traditional Local & Long Distance

Traditional phone companies and broadband service providers are competing to be your local phone and long distance carrier. It’s up to you to decide whether you keep a traditional land line or opt for the newer digital phone line. Either way, the competition means you’ve got more of a selection when it to choosing between phone service providers. Both services have their advantages, so only you can decide which local and long distance phone service is best for your home. Most every plan comes packed with features, so they’re “basic” in name only. Some calling plans even offer unlimited local and long distance calling along with popular calling features like Call Block, Priority Ringing, Caller ID and Call Waiting.

SIP Trunking Services

Some organizations have already made huge investments in legacy PBX phone systems. But they still want the benefits that come through converging all local and long distance phones systems and broadband Internet services onto one line. SIP Trunking allows businesses to reap VoIP-like benefits with legacy systems, without investing in new infrastructure. Using SIP, you can consolidate all your communication systems, including data and voice into one bill and a single point of contact.


Unified Communications as a Service (UCaaS) refers to a service model where providers deliver different telecom or communications software applications or services, generally over the global IP network.


The Primary Rate Interface (PRI) is a telecommunications interface standard used on an Integrated Services Digital Network (ISDN) for carrying multiple DS0 voice and data transmissions between the network and a user. PRI is the standard for providing telecommunication services to offices.


Because of the bandwidth efficiency and low costs that VoIP technology can provide, businesses are migrating from traditional copper-wire telephone systems to VoIP systems to reduce their monthly phone costs. VoIP solutions aimed at businesses have evolved into unified communications services that treat all communications—phone calls, faxes, voice mail, e-mail, Web conferences, and more that can all be delivered via any means and to any handset, including cellphones.

Hosted PBX

This technology allows small and medium-sized businesses to have a sophisticated telephone system without the investment in telephone equipment.  In fact, the entire telephone system is operated and maintained by your Voice-over-IP (VoIP) service provider.  A Hosted PBX lets employees work from their home, a hotel or on their cell phone while still being connected to the same office telephone system.  Just like a Fortune 500 telephone system, you can transfer callers, put them on hold with music, set up conference calls or have the phone answered by an automated attendant who can direct callers to different departments. 

Mobility/ Wireless

With more networks and more coverage, our enterprise-grade mobile solutions are designed to scale based on your business needs. From large, distributed workforces to multi-location retail outlets, Mobile Solutions provide nationwide coverage, delivered through the consolidation of the most trusted wireless networks (AT&T, Verizon, T-Mobile, and Sprint). 

Hosted ACD/IVR

Over the last ten years most of the IVR market has shifted to the cloud, and that’s created a lot of disruption.  If it’s been a few years since you’ve considered an IVR upgrade, you might be surprised to learn that the “usual suspects” for your vendor short list aren’t the usual suspects anymore.
