Agent Portal

NextivaONE, the agent portal unifying external communications and internal collaboration, offers an omnichannel dashboard where agents can monitor inboxes for voice messages, SMS texts, internal chat messages, and notifications for video meetings and calls.

The All Communications omnichannel inbox aggregates multichannel messages and notifications from customers and teammates with embedded voicemail playback, easy omnichannel callback, and the ability to sort notifications by message type or contact.

Tab switching allows agents to support many open conversations at once and change communication channels with one click.


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 Customer Perspective

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.

Agents can text images and regular SMS from their business number on Nextiva’s mobile or desktop app, with inbound customer texts routed as tickets to the right agent’s dashboard–logged as part of the multichannel conversation history and ready for one-click response.

Pre-built messaging templates format automated reminders to teammates.

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’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.
