I’m running FreePBX version 220.127.116.11 and have a question regarding calls from clients and authentication. I have a 2n Helios door station that I set the SIP Proxy to Asterisk. I enter invalid ID and password. I’m not enabling Registrar.
With this configuration I’m able to call other registered clients via Asterisk, even though the credentials are invalid. I’d expect Asterisk to authenticate the caller and reject the call based on the invalid credentials.
Is there a way to turn that on in Asterisk?
