DiaVoice vs Vonage
Vonage has been a household name in VoIP for over 20 years. They pioneered consumer VoIP and built a recognizable brand. Today Vonage Business Communications is their small and mid-size business product — and it is a solid platform with some real strengths and some real frustrations.
Pricing
Vonage Business starts around $19.99/user/month for the Mobile plan but this plan is stripped down — no desk phone support, no call groups, no visual voicemail. The Premium plan where most features live runs $29.99/user/month. Advanced is $39.99/user/month.
Unlike DiaVoice, Vonage charges extra for features like call recording, visual voicemail, and call groups on lower tiers. And Vonage is known for aggressive annual contract requirements with significant early termination fees.
DiaVoice DiaPBX is $20/user/month month-to-month with full features included. No contracts, no termination fees.

The Hardware Issue
Vonage has a documented history of hardware pricing issues. When customers have requested hardware quotes, desk phone pricing has come back significantly higher than market rate — with limited options for negotiation.
DiaVoice works with Grandstream IP phones at standard market pricing, or entirely without hardware through DiaVoice Go on any device.
