This is not about the drawbacks of a specific application. X-Lite is a
rather popular SIP client and my annoyance is caused by how people would
sometimes wave its behaviour as a de-facto standard.
The entire response from 1&1 shows lack of understanding of the problem,
or a reluctance to deal with it. What the "Incompatible SIP services"
page on Blink's site says is that the technique 1&1 expect clients to
use is outdated and does not always work. There are indeed many
scenarios where it would pull through, which is probably why they
consider X-Lite as "working" with their service.
This doesn't change anything to the fact that using STUN as a standalone
NAT traversal solution (and especially using it for SIP headers) is a
very lame solution that would often fail. To projects like Blink
implementing it would hence imply wasting resources so that part of the
users of a certain provider would be able to successfully connect to it.
