Common questions
Do I need to be technical to set this up?
You should be comfortable following technical steps, copying configuration values, and testing on a non-production number first. Setup time depends on your phone system, provider approvals, and carrier registration.
What does it cost to run per month?
Provider pricing changes and may include phone-number, message, carrier, registration, and campaign fees. Check the current Twilio or phone-system pricing before launch; the guide does not promise a fixed monthly cost.
Will this work with my existing phone system?
The playbook covers Twilio-native, RingCentral, OpenPhone, and compatible forwarding paths. It also explains why Google Voice should not be forwarded into this automation. If your provider differs, email us during the 90-day support period and we’ll help identify the closest documented path.
What if I want you to just do it for me?
Totally fair — that’s what Ohio Service Tech’s $299/mo Missed-Call Rescue managed service is for. If you buy the $47 guide and decide DIY isn’t for you, we credit the full $47 toward month 1 of the managed service.
Is there a refund policy?
If the guide is not useful for your setup, request a refund within 30 days of purchase. Access after a refund follows the checkout platform’s policy.
