A number assigned to one team member is their own line. Calls to it ring only that person in Genaya: the web app and the Genaya phone app. Nobody else on the team rings, and texts to it go to them.
Open the number under Operations -> Phone numbers. In When someone calls this number, pick Assign to a team member and choose the person. You can also do it from the member's page under Operations -> Team. A person has one personal number at a time, so giving them a new one releases their old one from them.
A number assigned before this choice existed keeps working as before: Genaya rings together with the cell phone on the person's profile, except when they use the Genaya phone app, which already rings their phone.
Our team typically replies within one business day.
