[OpenSER-Users] About the opensip server.

Hi, I am working in Nokia and now response for setup a openser sip server providing sip proxy and registrar for one of our project. After I have install the openser Sip server by following all the steps from CVS installation guide. When I start the sip server with openser start command, I always got: 'openser' start: /etc/init.d/openser Openser failed to start Strating open sip router: Listen on Udp: ... Aliases: Tcp: ... It seems the starting is failed. So could you tell me what could be the reason? Or could you please tell me is there someway I can test if my openser is running now? Thanks.
