Editor’s Bottom Line:
1-VoIP stands out from the pack with a very impressive 99.999% SLA. Their hosted PBX features are no more or no less than I would expect from a top-notch VoIP provider. Their SIP trunking rates are a good deal. Their residential service is average, but I’ve seen better prices on similar services.

Old technology that was not updated during the three years we had service with them.
New features were promised and never delivered.
Follow through on requests didnt happen as Panterra staff left to peruse careers with better employers.
Several major outages during our time with Panterra.
They had billing issues they couldn’t/wouldn’t work with the customer to work out.
Adds/moves/changes on Panterra platform difficult, unintuitive, and time consuming.
I asked for updated documentation for 3 years, which was ignored.
