ADTRAN’s NetVanta 7100 isn’t just an IP PBX, but a complete office-in-a-box solution that handles both data and voice networking. Designed for small to very small businesses, NetVanta 7100 is priced according to two licensing models: one bundled with 30 user licenses and another with 100. In other words, administrators with the 30-user package can add up to 30 employees without having to buy additional licenses. All features are included for each user, instead of being offered through an “à la carte” model in which users have to be licensed separately for certain features.
While NetVanta 7100 is an on-premise system, the graphical user interface is browser-based, so users can manage voicemail, fax messages and email using desktops or mobile devices. NetVanta 7100’s IP router functionality also allows businesses to extend data connections to multiple endpoints such as employee desktops. And the system can also support analog phones, fax machines and credit-card readers.

Not technically "software", the Adtran 7100 is a bespoke platform for running the Adtran Operating System (AOS). AOS provides a feature-rich call control platform and via integration with the 7100, a full featured all-in-one platform for delivering voice services. The 7100 combines a router with VPN capability and swappable interface modules, a 24 port layer 2/3 POE switch, and a feature rich PBX into a 1U chassis that is easy to deploy and maintain. While the platform can scale up to 100 users by adding additional switching capacity, the sweet spot is for Internet connected small and remote offices with VPN connectivity requirements and it makes a perfect office in a box solution at a fraction of the cost of other solutions.
Perfect applications scenarios are retail stores, construction trailers, fast food/quick service, banking, and any other scenario where you require an easily deployable solution for multiple locations. The 7100 can be quickly integrated into a corporate PBX using SIP trunks to allow toll bypass and a simplified dial plan.
Other great features:
The GUI is easy to use and allows you to control most of the functionality that is available in the CLI.
Powerful voice quality and service monitoring tools (VQM) are included.
In addition to supporting native Adtran endpoints, there is fairly broad support for industry standard Polycom phones.
It is an all-in-one solution . . . while this is a great selling point, it is also a single point of failure. Routing, switching, and telephony all resides in the same operating space so issues that are impactful to one may be to others as well.
While the AOS CLI is syntactically close to Cisco IOS, it is just different enough that you will find it frustrating if you are a Cisco CLI jockey.
Setup and configuration is about as simple as it gets, but you will be dealing with technical subjects so an understanding of networking and telephony is recommended.
Unheard of 5 year warranty.
Other manufacturers have similar capabilities, such as Cisco's Call Manager Express, but not typically at the same price point, and not as an all-in-one solution. If you are looking to integrate multiple remote sites with a corporate PBX it is worth looking at your existing vendors solutions and seeing if there are any advantages to using the same vendor end-to-end.
