[Serusers] about cisco 5x00

[Juha Heinanen]

since many people mentioned that they are using cisco 5x00 series
sip/pstn gateways, it would be nice if also others than me would push
cisco to implement digest authentication in its ios software.  currently
5x00 namely is the only sip UA that i'm aware of that doesn't support
digest (or any other) authentication of sip requests.

another annoying thing with 5x00 is that i cannot configure the host
part of its from uri.  it always uses as the host part the numeric ip
address of the interface via which it is sending out the sip request.
