Slack right in the OnSIP app

Are you ever on a conference call and need to shoot someone a quick message? No need to leave your call view— Slack your colleague (or channel) right in the OnSIP app. The Contacts sidebar displays your team’s phone and Slack presence. If they’re available for chat, you’ll see a chat icon next to their name. If the icon is green, they’re available for a call.
