Dear All, I have a small configuration, two Windows Mobile devices "WM5.0" and a SIP Proxy within the same WLAN. I managed to register the devices into the SIP proxy, but I cannot make calls. Whenever I try to do, I get a request timeout error. Attached are the two LOG files from the two mobile devices. Thanks, -- a. -------------- next part -------------- An HTML attachment was scrubbed...
