Ok, Christian, let's fix this.

First, I'm curious, is the "line=" parameter specified somewhere? (Always looking
for documentation :-)

Secondly, in many places in the sip channel, everything after the ";" is discarded.
I would really appreciate if Snom could help us fixing this, so Snom phones work correctly
and fully with Asterisk. (Have a new Snom 200 on my desk :-)

I'm not an experienced C programmer, so I can't fix this myself. However, there are
experienced C programmers in the community that will fix this, but they need proper
and detailed input on what to fix.

I've opened a bug
http://bugs.digium.com/bug_view_page.php?bug_id=0000732

Let's continue adding information there.

BTW, there's some other Snom problems where we need input from SNOM. Search on "Snom"
in the bug tracker. Thank you for participating in the Asterisk community!
