Good to know

Ruby is a US-based live receptionist service whose financial-services page is written to CPAs, tax professionals and advisors, and its AI works behind the receptionist rather than on the phone: Call Nav feeds them answers about your firm, calls and voicemails come back as AI transcripts with sentiment insights, and AI filters robocalls — all included in every plan. Plans run $250/mo for 50 receptionist minutes, $395 for 100, $720 for 200 and $1,725 for 500, with managed live chat from $143 and no setup or activation fees. 24/7 bilingual answering, appointment booking and a Ruby app to change handling instructions.
