Thanks Fred. If I understand correctly, when a document says "function returns
FALSE", it means it will return one of the negative numbers. I assume the expresion
"if(negative_number)" will be evaluated to be true in kamailio cnf.
In that case, the code
if (loose_route()) {
...
} else {
...
}
will never go to "else" block. So basically the code is wrong, right?
No.
If there is no Route header, it returns false. If there is, it returns true. If there is
no Route header the else section will be utilized.

Hello everyone,
While going through the WebRTC example configuration (cfg) to better understand and
implement it in my setup, I came across a potential issue in the code block. The code in
question can be found at this link:
https://github.com/kamailio/kamailio/blob/465994de2859c7863b4cef8457be0a207…
In the code, there is an "if else" block, "if(loose_route())" that
seems to be incorrect. It appears that the "if" block will always evaluate to
true, given that "loose_route" never returns 0. According to the documentation,
the return values of "loose_route" are specified as 1, 2, -1, -2, -3.
Therefore, it seems the "if" block is unnecessary, and the "else"
block will never be executed. Could someone please confirm this observation and, if
accurate, suggest a correction for the code?
Thank you for your attention to this matter.
Best regards,
Pavan Kumar
1,2 would be a true response.
-1,-2,-3 would be a false response.

" If there is no Route: header, the function returns FALSE and routing should be
done with normal lookup functions. If a Route: header is found, the function returns 1 and
behaves as described in section 16.12 of RFC 3261. There is only one exception: If the
request is out-of-dialog (no to-tag) and there is only one Route: header indicating the
local proxy, then the Route: header is removed and the function returns FALSE."
