Keep everyone on the same page with OpenPhone and Slack

Monitor spikes in calls and texts

Protect your team's time and ensure colleagues outside of your OpenPhone workspace are in the loop.  OpenPhone’s Slack integration lets you automatically push new missed call, voice, and SMS text message notifications to any Slack channel. With all the data in one place, easily track spikes in volume, adjust schedules, and pivot to all hands on deck.

Prioritize specific conversations

During the day or after hours, the OpenPhone Slack integration lets you quickly review notifications to identify conversations that require an immediate response. Then, tag team members for clear ownership of follow ups. Need to circle back a bit later? You can even set time-based reminders in Slack — and conversations never slip through the cracks.

Save time on voicemail follow ups

Your team doesn’t need to drop everything else to playback voicemail recordings. Slack's OpenPhone integration transcribes voicemails to text. Slack users can quickly review incoming messages and gauge if they need to call them back immediately,
