I have established a server with SER on the Internat with the
IP:194.165.196.72,And we also have our own hardware phone developed. I am using
MySQL and the nathelper modules & RTPproxy with NAT,but I run accross 2
problems with the digest authenticaiton:</SPAN></FONT></B></P>

on the server: I tested K-phone,X-Lite,WM5 and our own hardware phone,but with
the digest authentication mode only the K-phone and X-lite can log in ,our own
hardware phone and WM5 cann't register on it. The K-phone log on it with
challenge form and password,fill in the password then log on.but the WM5 even
haven't the challenge form to fill in the password.our own hardware phone also
cann't log on the server.</SPAN></FONT></B></P>

phone problem: Our own phone supports SIP/MGCP/H.323/Net2phoen protocals ,like
Cisco ATA and 7960 products and have more features.But Also under non-digest
authentication mode,It can regist and log on normally but while make a
call behind NAT with RTPs,between X-lite,cann't hear the voice on the PC,but all
can speak on the hardware phoen while X-LITE call to the phone.When Phone call
to X-lite,it just the same,cann't hear anythink on the PC but other works
normally.(Two UAs are all behind NAT).</SPAN></FONT></B></P>
