Hey, I tried implementing browser-to-phone calling. Initially, the call would ring successfully, but after a few days, when I tried again using the same codebase, I started getting a 603 Decline error.
I tried debugging the issue but haven’t been able to figure out the cause or fix it. Could someone please help me understand why this is happening and how I can resolve it?
Also, I noticed that my request first shows as “Trying” and then gets declined. Does this mean that my provider (IAGU) or the SIP trunk provider is sending the 603 Decline response?
If yes, why would this happen, and how can I troubleshoot or fix it?
