Prevent Call Looping

Edited

Call looping occurs when:

ANET transfers back to a number that forwards to ANET
Return line is misconfigured
Conditional forwarding rules overlap

How to Validate Loop Prevention

Confirm forwarding rule only applies to external inbound calls.
Confirm return line has zero forwarding.
Place test call:
- Trigger transfer.
- Confirm call does not re-enter ANET.
Monitor timeline for repeated transfer cycles.

Looping must be resolved before go-live.
