Bria Solo
Connect the Bria Solo softphone on a computer or mobile to a SIP device on your PBX.
Bria Solo is a paid third-party softphone for desktop and mobile. You set up the connection once in your online Bria Solo account, then sign in to the Bria app on each computer or phone. Bria’s subscription isn’t part of your PBX service.
