OnSIP Messaging and Collaboration

OnSIP does not offer any digital messaging channels, like SMS or web chat.

However, OnSIP does offer Sayso, a website-embedded button widget that instantly connects site visitors with your available staff agents via phone or video. While traditional inbound customer calls require a customer to dial the company phone number and wait through the queuing system, Sayso connects website visitors–both customers and leads–to a staff agent instantly.

Customers choose video or voice, select a conversation topic, and begin.

Sayso provides agents with contextual details:

• Topic
• Web page called from
• Web page viewing history
• Caller location
• CRM record–name, email, phone number

If no agent is available, customers leave their name, phone number, and best callback time. Agents receive the notification with full context and call back at the right time.

Sayso offers a free Starter plan and a paid Pro plan with added features, like analytics and screen sharing.

Nextiva Messaging and Collaboration

NextivaONE enables internal team messaging and SMS texting to teammates or external customers, just by clicking on a user’s name, profile, or phone number.

OnSIP vs Nextiva: Pricing and Plans

OnSIP’s Unlimited Plan costs $18.95 monthly per user and offers unlimited calling within their 20-country calling area. Its VoIP system also includes unlimited usage of most features, like auto attendants and ring groups.

The Basic plan, best for small companies with low call volumes, costs $49.95 per month for the entire account, but charges 2.9¢ per minute for calls and includes limited usage of features.

Many call-center features, as well as Sayso, are available as add-ons.

Nextiva’s Essential plan includes unlimited voice calling within the US and Canada, along with chat and video. The Professional plan adds conference calling to the VoIP service, expands the auto attendant to multi-level, and adds SMS capabilities. The Enterprise plan includes all integrations, access to many Nextiva automations, and call recording.

Nextiva’s advanced analytics features–like in-depth queue reports and visuals, real-time agent suggestions, and customer journey mapping–and their productivity features–like unlimited teammate rooms, video chat, and video recording–are available as separate add-on plans.

OnSIP Pros & Cons

OnSIP’s Basic plan offers an affordable whole-account pricing structure for small teams that can share features like auto attendants and call recording. Their unlimited calling network is larger than most competitors.

However, the fact that OnSIP lacks digital messaging channels is a major drawback, and their integration options are limited.

Nextiva Pros & Cons

Nextiva’s automations and analytics facilitate strong sales and customer support use cases, with options for automated surveys, reminders, and follow-up messages. Further, Nextiva’s basic plan includes chat and large video conferences hosting up to 250 participants.

On the flip side, Nextiva’s higher-tier plans quickly add up in price, and their most useful analytics require an add-on package.
