DiaVoice vs Nextiva
Nextiva is one of the most recognized names in business VoIP. They have built a strong brand, solid infrastructure, and an impressive feature set. They are also one of the most common providers that small businesses switch away from — usually because of billing surprises.
Pricing — What You See vs What You Pay
Nextiva's Core plan starts at $30/user/month. The Professional plan — where most of the features businesses actually need live — runs $40/user/month. Enterprise is $60/user/month. And those are the annual billing prices. Month-to-month rates are higher.
Then add: taxes, regulatory fees, add-ons for features that sound like they should be included, and the hardware costs if you need desk phones.
DiaVoice DiaPBX is $20/user/month. DiaVoice AI starts at $15/month. DiaFax is $34/month. DiaCRM is $39/month. No annual commitment. No surprise fees. What you see is what you pay.

Feature Deep Dive
AI Receptionist
Nextiva has added AI features to their higher tiers — AI summaries, AI analytics. But a true 24/7 conversational AI receptionist that answers and routes calls is not a standard Nextiva feature at small business pricing. DiaVoice AI is a full conversational AI receptionist available as a standalone product starting at $15/month.
CRM Integration
Nextiva integrates with Salesforce, HubSpot, and other CRMs through their higher-tier plans. Those integrations work through APIs — which means configuration, maintenance, and another subscription to manage. DiaVoice DiaCRM is built directly into the platform. No API. No integration. Same dashboard, same data layer, zero configuration.
eFax
Nextiva includes online faxing on higher-tier plans. It is not HIPAA-compliant on the base tier. DiaFax is HIPAA-compliant with BAA available as a standalone product at $34/month.
Contracts
Nextiva pushes hard for annual contracts and the pricing difference between annual and monthly is significant. DiaVoice is month-to-month, period.
