[Users] users in the same OpenSer cant call each other

Hello My Openser users can call PSTN numbers through a PSTN gateway. But they cant call each other dialing the usernames. Where is the bug in my config? here is my openser.cfg route{ if (!mf_process_maxfwd_header("10")) { sl_send_reply("483","Too Many Hops"); exit; }; if (msg:len >= 2048 ) { sl_send_reply("513", "Message too big"); exit; }; if (!method=="REGISTER") record_route(); if (loose_route()) { # mark routing logic in request append_hf("P-hint: rr-enforced\r\n"); route(1); }; # -------------------------------------------------- # Registration # -------------------------------------------------- if (uri==myself) { if (method=="REGISTER") { # Uncomment this if you want to use digest authentication if (!www_authorize("myserver.com", "subscriber")) { www_challenge("myserver.com", "0"); exit; }; save("location"); exit; }; } if (is_method("INVITE")) { # Route E.164 numbers to PSTN Gateway if (uri=~"sip:\+[1-9][0-9]*@myserver.com" ) { if (isflagset(29)){ route(2); return; } } # Route E.164 numbers to PSTN Gateway if (uri=~"sip:[1-9][0-9]*@myserver.com" ) { if (isflagset(29)){ route(2); return; } } } # method = invite route(1); } route[1] { # send it out now; use stateful forwarding as it works reliably # even for UDP2TCP if (!t_relay()) { sl_reply_error(); }; exit; } # Gateway PSTN route[2] { rewritehost("gateways_IP"); t_on_reply("1"); if (!t_relay()) { sl_reply_error(); }; } Thanks for the help Joao Pereira
