Blocking duplicate calls from the same source.

So after some more testing, it appears as things are not working correctly. The calls are in fact still being blocked, I thought it was just the different priorities that were coming from the same SIP:To address, but that is not the case. It is still blocking the 2nd call intermittently, even if the call is cancelled first. I find it weird that it sometimes works and other times not. I even added another option within the nurse call to cancel and resend a different invite a 3rd time and it also works intermittently.

I wish I could send you some wireshark logs to help out here, but I can't seem to attach anything on this forum.

Whenever I add the $istalking( To ) =^True rule, it doesn't block anything. Or I am not seeing after 3-4 days of testing that it showed a single error in the logs.

Hi,

I have a newer (What I believe to be simpler) request.

Is it possible to have an active session automatically force cancel if a new call comes in using the exact same parameters?

This way the new call gets processed as an active session, instead of the new call sending back a 486 busy here?

What does "same parameters" mean?
Same SIP header value? same To-URI and/or same Request line?

Same SIP-To URI, and same From-URI,

It requires a custom plugin.
Let you discuss it with support@brekeke.com.
