Forward the calls you miss, and fix the three iPhone features that can silently get in the way.
Go to Settings → Apps → Phone → Call Forwarding (older iOS: Settings → Phone → Call Forwarding). Turn it on, tap Forward To, and paste your Relayra number. This sends every call to Relayra — the path Apple documents.
Common on Verizon. Dial *72 + your Relayra number for every call, or *71 + number for missed/busy only. Dial *73 to turn off.
iPhone Settings can’t do “only when I miss.” Use a carrier dial code instead (AT&T/T-Mobile: **61*number#). Full walkthrough with tap-to-copy: call-forwarding guide.
On iOS 17 and later, Live Voicemail answers unanswered calls on your iPhone to show a live transcript — which means the call never rings out to your carrier, and missed-call forwarding never triggers. Turn it off: Settings → Phone → Live Voicemail.
Found at Settings → Phone → Silence Unknown Callers. With forwarding on, silenced unknown callers divert to Relayra — which is fine for customers. The catch: Relayra's own owner-transfer calls may come from a number that's not in your Contacts, and those would get silenced too. Either keep this off, or save every Relayra number to Contacts first (Part 3).
Focus and Do Not Disturb don't break forwarding — a silenced call still rings out and reaches Relayra. But a Focus will silence Relayra's transfer calls and summary texts to you. In Settings → Focus → [your work Focus] → People, allow calls and notifications from your Relayra contacts. "Allow Repeated Calls" is a good backstop too.
Add your Relayra business number, the number that sends your alert texts, and any owner-transfer number. Suggested names: Relayra Business Line, Relayra Alerts, Relayra Owner Transfer. This is what makes steps 2 and 3 of Part 2 safe.
From another phone, call your business number and don't pick up. Relayra should answer with your greeting, and your summary text should arrive right after the caller hangs up. If voicemail answers instead, revisit Part 2, step 1.
