04Is OnSIP worth the money?
OnSIP is worth considering if you want hosted calling and can match the plan to your usage. Unlimited’s $18.95 per-user rate needs to be weighed against its five-user minimum and 250-message account allowance. Basic avoids an included-minute commitment, but 3.2¢ per minute and paid features can make costs harder to forecast. The pricing grid lists many extras separately and no annual discount; price the queues, recording and numbers you need before switching.
