The best way to handle this is using a static trusted IP trunk rather than trying to spoof digest authentication mechanisms or fool the location service.

Hi there,

I turned up a few new sip trunk customers this past week, from which one of them was an Avaya system. The customer wasn’t able to do a username/password auth, so I set th em up as a permanent entry in the location table. I am running Kamai lio 1.5.5.

The issue is that I am throwing back a 404 to them when they do a timer event, as they are passing sip:Unknown@my.ip.addr. I don’t have a user name Unknown, hence the 404. I noticed that with the timer events from other customer’s PBXs, that they are passing sip:my.addr, from which I am giving back 200 OK.

What is the best way to handle this? Just let it go or add a “Unkno wn” user (I don’t like the latter, really)? Calls to and from their system is fine, so right now it’s just entries in my logs – but I hate spending CPU cycles on stuff that isn’t going to benefit anyone. I sent an email back to the customer to see if maybe he can resolve it on his end, but I am doubtful on getting it resolved on his end.

Thanks,
