Hi everyone: I am trying to setup SER and Asterisk in one box.I used SER to deal with SIP packet and used Asterisk to handle RTP packet,because I want implement Voicemail/conference/Holdonmusic and so on,in my soft swith system.I am implemented basic things seems already.But I found some big problems. If I let SER outbound up.The register infomation will bypass [location] table on SER.Why is happened? And I am confused about the relationship between SER and Asterisk?How SIP packet flow through them ? Thanks for reading Regards edison
