What Is a Local Partner, And Why Do I Need One?
Major VoIP vendors generally use local partners to deploy and provide support for their solutions. This is the case whether their systems are located on your business’s premises or in the cloud.
Vendors use partners (also known as systems integrators) because setting up a VoIP system demands lots of IT experience with voice networking and the technical specifications of a particular brand of system.
While large companies have the IT resources to deploy phone systems on their own, you probably don’t. Moreover, even major companies rely heavily on local partners to deliver circuits, drop cables and resolve configuration issues.
Avaya Partners
Avaya has been a leading provider of business phone systems and unified communications (UC) solutions for over a decade. In addition to basic telephony features, UC systems offer user interfaces that bring together multiple modes of communication (voice, video, instant messaging etc.) on multiple devices ranging from desk phones and smartphones to softphones.
Avaya’s product line serves small businesses to enterprises. The IP Office solution in particular is designed for smaller businesses. Avaya also offers contact center solutions and conferencing solutions.

Nextiva Partners
Whereas many of Avaya’s solutions use hardware installed on your business’s premises, Nextiva’s phone system and contact center offerings are cloud-based. Nextiva is known as one of the more feature-rich and easy-to-use cloud platforms on the market (you can read user reviews on our site).
One advantage of using a cloud system like Nextiva is that you don’t have to lock yourself into a contract; you simply pay on a month-to-month basis.
You’ll still need a partner to handle cable drops, configuration and support even with a cloud system like Nextiva’s. Thankfully, you’ve got some options in the Chicago area:

ShoreTel’s on-premise VoIP solutions utilize a unique hardware architecture that enables phone systems at branch sites to keep running independently if the server at the main corporate location goes down. This makes ShoreTel a good choice for businesses with multiple locations.
