About CareOS Phone
CareOS Softphone turns your mobile phone into a full extension of your business PBX. Receive and make internal and external calls with professional quality, wherever you are.
Developed by Internal·IA Intelligence Solutions for business environments that need true mobility without sacrificing existing SIP infrastructure.
