Hello to everybody.
I am currently working with Kamailio 3.3.1 on RedHat.
The "loose_route" function was not working correctly and I observed some very
strange behaviour (not as one described in the documentation of the function).
I have found that there needs to be a port included in the "alias" variable for
the loose_route function to work correctly.
However, upon adding the port to alias, the INVITE messages were no longer
authenticated (Kamailio just accepted them and didn't send proxy-auth header in
407 message).
My alias:
alias="domain.ch:5060"
Examining default routing logic, I found the problem here:
if (is_method("REGISTER") || from_uri==myself)
{
# authenticate requests
...
}
The "from_uri==myself" was no longer evaluated as true, because there was a
port at the end of the alias.
The FROM Header of the INVITE messages looks like:
From: "acc1" ;tag=12345
..so .. no port number there.
Btw, I have fixed this with replacing the "myself" list with my own defined
variable MY_DOMAIN.
#!define MY_DOMAIN ".*@domain.ch"
So now the condition looks like this:
if (is_method("REGISTER") || from_uri=~MY_DOMAIN)
{
...
}
I am not sure if this is a bug that needs to be fixed or not. I am just
pointing my finger at it and I hope it will contribute to the development.
Also, a valid description of this behavior (when using port in alias) would be
appreciated.
Cheers,
Martin
