What We Like About the Service

Certainly, there are too many things to like about OnSIP but some are simply too impressive. The specific things that we like so much about this service are as follows:

The Pay as You Use Plan

This is one of the highlights of the OnSIP VoIP phone system. It ensures that businesses are not spending more than they should on telephony services. Though it includes a minimum monthly plan, it is still a great option for budget-conscious businesses.

Smooth Video Calling

With OnSIP, video calling is a lot better than what you can get with other providers. The video qualities are often impressive and this can meaningfully improve collaboration in your organization.

Availability of Multiple Plans

What is more attractive than a pay as you use plan? Well, some businesses may need other things and OnSIP understands that perfectly. There are several other pricing options and businesses can always find the perfect plan that will help them save more.

InstaCall is a feature that allows website visitors to place calls directly from their browsers and OnSIP supports it. This can help you to increase conversion rates and sales in a dramatic manner.

Impressive Customer Service

In addition to the number of amazing features they offer their customers, OnSIP is always ready to help. The customer service is highly rated by users. They are often able to find solutions to issues. Even when the issues are tough, they help by following up to ensure that they are settled at last.

What We Don’t Like About This Service

As much as OnSIP offers very wonderful service, there are few limitations we will like to point out here:

Paying for All The a la carte Features Can Really Add Up

While there are several other features you can get in addition to the basic ones you are offered for your plan, paying for most of them can add up too quickly. You may realize you have to pay more than how you imagined in order to use all the features you like.

It Requires A Little Knowledge of the SIP Protocol

Though setting up and managing the account is pretty easy, a little knowledge of SIP is needed and a novice will need some time to learn. The support team is always helpful, though.

No Faxing Available

OnSIP provides a wide array of features but sadly faxing is not one of them. Faxing is vital to today’s businesses meaning that those with this need will have to arrange for a dedicated fax service on top of getting OnSIP.
