hi all, When I start the UAS on port 2080 and register with the UAC on port 5060,it returns 200OK . But I can not make a call,the invite MESSAGE has been send to the UAS, but no "trying" returned. Then I found the destination port in invite MESSAGE uses the defualt port 5060 but not the 2080,is it the reason? And if not,how to resolve the problem? thanks ! 2008-04-14 liangjiuqin -------------- next part -------------- An HTML attachment was scrubbed...
