I bought a Siemens Gigaset C475IP at the beginning of this year.

RFC2833 dialling is broken, because it has broken handling of RTP
mappings. If the peer doesn't ask for RFC2833 data in the same payload
type as the C475 does (which it SHOULD but some don't), the C475 ignores
the peer's rtpmap and just sends DTMF with the same payload type it
asked to *receive* it in.

I spent *months* trying to get a coherent response from Gigaset support
and failing. Eventually when I filed a complaint about the lack of
response, they told me they wouldn't fix it. They did say they'd replace
it with a newer device.... but then have so far failed to follow through
on that either.

I won't be buying another Gigaset, and wouldn't recommend them either.
