Business VoIP landlines
VoIP, without the price tag
Stop paying landline prices for a landline service. Black Tie VoIP gives your business a real local number, clear calls and a monthly bill you can predict, over the internet connection you already have.
Choose a single line for a home office, a hosted PBX extension for each team member, or connect your existing PBX hardware over a trunk with DID. Every option bills true per-second, with no long-term contract.
