Sync your accounting, take payments online, message customers, and wire up your own systems — with a public API and webhooks when you need to go further.
We built our own cloud PBX instead of bolting on someone else’s. Calls and texts run on one system — no PBX box and no extra phone vendor. It does what a full office phone system does — menus, queues, extensions, park, paging, voicemail, fax — and because it lives inside MEPSub, the customer and their open work orders pop up before you answer and every call, recording and voicemail lands on the job.
MEPSub Phone is rolling out to workspaces now. Tell us how many people answer the phone and we’ll get your number and call flow set up with you — or keep the number you already text from.
Every package includes local number(s), US & Canada calling, texting, call recording, voicemail with transcription, phone menu, ring groups, business hours and screen-pop. One-time $49 setup · extra user or number $5/mo · over the allowance $0.02 per minute or text. AI receptionist add-on $99/mo with 500 AI minutes. Launch pricing for early-access workspaces.
Emergency calls: the MEPSub browser phone can’t dial 911 — keep a cell or landline for emergencies.
