480Temporarily Unavailable

"Hello everyone,

I’ve set up a system based on **Drachtio** for making SIP calls. Outgoing calls work correctly.

However, in cases of **“Temporarily Unavailable”**, the response code returned is **503 Service Unavailable** instead of the expected code **480 Temporarily Unavailable**.

Has anyone else encountered this behavior or could point me in the right direction?"
