A1Phone FAQ

Questions about the A1Phone softphone

What is A1Phone?

A1Phone is A1ROUTES' softphone — a desktop app that turns a computer into a business phone for Cloud PBX and SIP calling, with call handling, HD audio and encryption built in.

Which platforms does A1Phone support?

A Windows installer is available for download. Because A1Phone uses standard SIP, the same A1ROUTES credentials also work in most third-party softphones if you need another platform.

How do I set up A1Phone?

Download the app, then add your account using the SIP credentials A1ROUTES issued (username, password and domain). Our step-by-step guide walks through it.

Do I need an A1ROUTES account to use A1Phone?

Yes. A1Phone registers to an A1ROUTES Cloud PBX extension or SIP account. Contact us to get set up with a number, extension and credentials.

Is A1Phone secure?

Yes. A1Phone supports encrypted SIP over TLS and SRTP media encryption, and each user is issued their own credentials.

Can several agents use A1Phone?

Yes. Each agent signs in with their own extension and credentials on the A1ROUTES Cloud PBX, so a whole team can run from A1Phone.
