I installed sip-jabber gateway,IP of sip server is 192.168.0.227,sip client is message 4.6.And IP of jabber server is 192.168.0.210,sip client is psi.Both of servers have no DNS . I have some question: I have been able to chat with presence between jabberd and MSN, and also I could chat between SER and jabberd with presence. psi <-> jabberd (msn-transport) <-> MSN <-> MSN Messenger Windows Messenger <-> SER (jabber.so) <-> jabberd <->psi When I try to connect other MSN user, I can login to MSN for my account, Windows Messenger -> SER (jabber.so) -> jabberd (msn-transport) -> MSN (my account) But I can't connect to other MSN user. Windows Messenger -> SER (jabber.so) -> jabberd (msn-transport) -> MSN (my account) - X -> other MSN user At the same time I can connect to other ICQ,AIM users. But the other ICQ,AIM user cann't connect to me. my ser.cfg is: /* Uncomment these lines to enter debugging mode */ debug=9 fork=no log_stderror=yes check_via=no # (cmd. line: -v) dns=no # (cmd. line: -r) rev_dns=no # (cmd. line: -R) port=5060 children=4 listen=192.168.0.227 fifo="/tmp/ser_fifo" # ------------------ module loading ---------------------------------- # Uncomment this if you want to use SQL database loadmodule "/usr/lib/ser/modules/mysql.so" loadmodule "/usr/lib/ser/modules/print.so" loadmodule "/usr/lib/ser/modules/textops.so" loadmodule "/usr/lib/ser/modules/sl.so" #loadmodule "/usr/lib/ser/modules/im.so" loadmodule "/usr/lib/ser/modules/tm.so" loadmodule "/usr/lib/ser/modules/rr.so" loadmodule "/usr/lib/ser/modules/maxfwd.so" loadmodule "/usr/lib/ser/modules/usrloc.so" loadmodule "/usr/lib/ser/modules/registrar.so" loadmodule "/usr/lib/ser/modules/pa.so" loadmodule "/usr/lib/ser/modules/jabber.so" # Uncomment this if you want digest authentication # mysql.so must be loaded !
