SIP
483 Too Many Hops
The Max-Forwards header has reached zero, indicating the request has passed through too many proxies.
Quando você vê este código
When a request traverses more proxies than the Max-Forwards counter allows (default 70). Often indicates a routing loop.
Como corrigir
Check for routing loops. If the path is legitimately long, increase Max-Forwards. Usually indicates misconfigured routing.
