Once known as Junction Networks, OnSIP delivers real-time communications to more than 50,000 companies. They endeavor to eliminate the cost restraints of traditional calling by offering businesses with a more flexible, scalable and affordable communications solution.





The Pros

The system itself comes with more than 50 calling features, flexible configuration options and a number of different payment terms.  The company outpaces it’s closest competition by offering three (well, technically four, but we will get to that in a minute) pricing plans to choose from. This flexibility allows smaller businesses to choose a phone system based on their unique needs – and not based solely on what a provider ‘thinks they should have.’

Each of the pricing plans offered by OnSIP allow businesses to reap the benefits of unlimited extensions, but they differ greatly based on how additional features are paid for. For example, under the ‘Pay as You Go’ plan, each extension is required to purchase additional features a la carte.

The Pay As You Go plan comes with five voicemail boxes, three auto attendants, three different ring groups, a dial-by-name directory and five hold channels and no cost. Outside of that, any other feature needed will come at a added monthly fee. This plan commences at $49.95 per month, per user and would be the ideal option for have a need for internal phone lines but don’t really use a lot of features.

Next, the Per Seat Metered plan includes a voicemail box, an auto attendant, a ring group, a dial-by-name directory, a greeting, busy lamp, hold music for $8.95 per user per month, with a minimum of 5 users. These same features on the Pay As You Go plan would quickly surpass $100 per user.  This is the best solution for businesses that need multiple full featured phones.

Lastly, the Unlimited plan offers everything in the metered plan, as well as unlimited calling and call recording and comes at a cost of $24.95 per month, per user.

An impressive selection of IP phones can be purchased from the company at a 30% discount and all come preconfigured.

The Cons

  • Some customers report installation instructions being a little too ‘technical’ for the average user.

When all is said and done, OnSIP offers a great platform for small and midsized businesses that need flexibility and the freedom to pick their price. Each of the paid platforms presents SMBs with unlimited extensions and a number of other free features but then asks them to customize their plans by choosing the features that they will use regularly.

There are both advantages and disadvantages to this. The advantage is that businesses aren’t locked into paying for things they simply won’t use. This allows companies (especially smaller companies) to control their spending by choosing a solution that meets both operational and budget needs.
