[Serusers] SIP Requests getting matched on my Transparent Web Proxy.

Hi All, A new user here, I m using 0.8.11, with default conf file shipped with package.without auth. While my softphone registers with the proxy, it gets listed in "serctl ul show", but another user while joins through same proxy with all other params same except username. The two cannt dial eachother.their addresses URIs are 12345(a)xxx.yyy.com and 22222(a)xxx.yyy.com, while caller,callee and proxy are in same IP subnet. They gett Timeout message. Can anyone give any idea? Thanks in Adv. JF --------------------------------- Do you Yahoo!? The New Yahoo! Shopping - with improved product search
