I set my freeswitch with the directory database, now by registering my extensions are connected correctly, but when making a call of the extension extention 1 to 2 me throws the following error "01/27/2015 10: 22: 35.158536 [ERR] mod_dptools.c: 3977 No dial-string available, Please check your user directory." and directly sends the voice mailbox of the extension. Thanks!
