Hi!
I have problems receiving calls when I'm registered to iptel.org using
Windows Messenger 4.7 (which usually workes fine).
Every incoming INVITE will be answered with a 400 Bad Request by
Messenger. It is independent from the caller's user agent (tested with
messenger and xlite). Furthermore, if the caller dials to me directly
without using iptel's proxy it also works. Therefore, I think the
problem is related to iptel's proxy.
Below is the dump of the incoming INVITE which is a Bad Request (says
Messenger). I couldn't find any problems, accept that the
Proxy-Authorization: header is still present.
regards,
klaus
