OnSIP Pricing

If you're comparing hosted VoIP providers, you'll notice that it's common for providers to offer "unlimited" service for a flat rate per person or per phone. While "unlimited" plans may sound tempting, they're often not worth the price.

With OnSIP, you pay for the PSTN minutes you use and each of the extra features you want.

Hook up as many phones as you'd like without worrying about underutilizing them. You can have a phone at work and one away from the office without being double-charged.
