Competitive Pricing and Terms

With each plan, you have the option of adding any feature on an a la carte basis. Prices for the a la carte apps run from $2 for additional voicemail boxes to $50 for a conference suite.
There are no contracts with OnSIP. You can cancel at any time without penalty. The company also offers a 30-day free trial.
Overall, OnSIP offers more than 50 features and tools. Some of those features are included in certain plans, while others are purchased on an a la carte basis.
- OnSIP's free plan includes web voice and video calling, unlimited extensions, web call buttons and links, web phones, presence, Slack integration, a Chrome extension, Zendesk integration, and business hour rules.
- Features in the Pay as You Go plan include everything in the free plan plus external calling, five voicemail boxes, three auto attendants, three ring groups, one dial-by-name directory, one announcement, five hold-music channels and one call-recording user.
- Features in the Metered User plan include everything in the Pay as You Go plan, plus each user can access voicemail, auto attendants, ring groups, enhanced hold music, Busy Lamp Field and call parking.
- Features in the Unlimited User plan include everything in the Metered User plan plus call recording.
Features you can purchase on an a la carte basis include voicemail, hold music, an auto attendant, a ring group, a dial-by-name directory, call recording, a simple or enhanced queue and dashboard, announcement, enhanced hold music, Busy Lamp Field, inbound bridge, and call parking.
OnSIP has a complete conference calling service built into its phone system. With the conference bridge feature, which costs extra, employees have the ability to hold their own conference call with up to 15 callers. If your company is looking to host conference calls with more people than this phone system provides for, you will need to use a conference calling service. These services allow for hundreds, sometimes thousands, of people on each call. You can find more information on these services on our conference call services best picks page.
There are several other reasons that OnSIP is a business phone system worth considering:
- It can integrate with many CRM solutions, including Highrise, Odoo and Zendesk.
- It works with any SIP desk phone. If you purchase five or more phones from OnSIP, you receive $300 in credit.
- OnSIP uses redundant servers, routers, Tier 1 internet connections and upstream carriers to provide extremely reliable VoIP service. It also has two data centers – one in New York and one in California – to ensure the system is always up and running.
- OnSIP offers InstaCall, a tool that lets visitors to your website make video calls to your sales or support team straight from their browsers.
- OnSIP is an accredited member of the Better Business Bureau with an A+ rating. No complaints have been filed against the company in the past three years.
OnSIP's mobile app, available for iOS and Android devices, is still in the beta testing phase. This means OnSIP is still working out the kinks. For those not wanting to use the app while it is still being tested, you can download a compatible third-party app, some of which cost extra, and log in with your OnSIP credentials.
Another negative is that conference calling costs extra for all plans. Many other providers include conference calling for no additional charge.
Free plan users should be aware that they don't have access to the customer support team if a problem arises. They must rely on the knowledgebase for help.
