Business Phone Systems

Overview

Business Phone Systems from a local Erie team

ETG has been Erie’s phone system specialist since 1993 and a Certified ESI Reseller since 2012. We’ll help you decide honestly between a new cloud or on-premises system and keeping the one you have, then install it, program it and service it for as long as you use it.

New systems from ESI

ESI systems come three ways: in the cloud (ESI eCloud PBX), on-premises (the eSIP Evolution Series, which you can own outright or rent monthly bundled with SIP lines), or premises + cloud. Desk phones, a smartphone app and a desktop softphone all share one extension, and the Verbal User Guide on ESI desk phones explains any feature at the press of the help key. Ask for a free on-site demo.

Keeping older systems running

Have a Nortel, NEC, Avaya or ComDial system? Don’t fall for scare tactics. ETG started out selling and servicing Nortel and ComDial key systems in 1993. Most of the time these systems need a simple adjustment or configuration change, not a replacement, and we can upgrade them to add features and reliability.

Hosted, cloud and SIP

If a cloud system makes more sense, we work with the major hosted VoIP providers and can move your lines to SIP trunking so you only pay for the lines you use.

FAQ

Questions about Business Phone Systems

All FAQs

Can ETG service a phone system you didn’t install?

Yes. ETG repairs and maintains existing telephone systems regardless of who installed them. If another company can’t or won’t service your system, call ETG for a second opinion.

Do I have to replace my old Avaya, Nortel or NEC phone system?

Usually not. Most older systems just need an adjustment, a configuration change or a routine repair. ETG still services Avaya, Nortel and NEC systems and can upgrade them to add features and reliability. If replacement really is the better choice, we’ll explain why and show you the options.

Can you add features to my existing phone system instead of replacing it?

Often, yes. ETG has reprogrammed older systems to deliver features customers were told required a new system, saving them the cost of a replacement.

What phone systems does ETG sell?

ETG has been a Certified ESI Reseller since 2012, selling ESI cloud, on-premises and premises + cloud systems. ETG also works with the major hosted VoIP providers, including RingCentral, Vonage, Nextiva and Toshiba VIPedge.

Can our phone system work with Microsoft Teams or our CRM?

Yes, with ESI’s cloud system. The eTeams Connector lets staff call from Microsoft Teams using their business numbers, and CommConnect links calls to popular CRMs so caller details pop up on screen.

Can I take my office extension with me on my cell phone?

Yes. ESI’s smartphone and desktop apps put your office extension on your cell phone or computer, with transfer, hold, voicemail, call recording and presence status, so callers reach you the same way wherever you are.

Should I choose a hosted (cloud) phone system or an on-premises system?

It depends on your building, your internet connection, how mobile your staff are and how you prefer to pay. Hosted systems put the phone switch in the cloud with a monthly fee; on-premises systems keep equipment in your building that you own. ETG sells and supports both, and will recommend the one that fits rather than the one that pays best.

Do you sell headsets and music on hold?

Yes. ETG supplies Bluetooth headsets that work with ESI desk phones, and music-on-hold systems. Mention them when you request a quote.
