A phone call redirect loop occurs when a call to one number gets routed to a second number, which then redirects back to the first number, creating a circular routing problem.
According to the article, evidence includes:
1. User Phone Number Check
Navigate to Subaccount > Settings > My Staff and verify that each user's phone number differs from their Scalendo-assigned number. Matching numbers create self-referential forwarding loops.
2. Forwarding Number Configuration
In Subaccount > Settings > Phone Numbers, ensure the forwarding destination differs from the main phone number itself.
3. Business Profile Phone Verification
Check Subaccount > Settings > Business Profile > Business Phone. The article recommends testing this number by calling it directly to confirm it doesn't inadvertently route back to the Scalendo number.
The core principle: ensure no phone number in your system points back to itself, either directly or indirectly through the forwarding chain.
