I just started freeswitch 1.4.5 on ubuntu 14.04 x64 and tried to connect SIP phone to freeswitch, but it is not registering. I am using default configuration.
I am using 1001 as username. 1234 as password and 192.168.1.5 as domain on sip phone. Machine on which freeswitch is installed has local ip 192.168.1.5.
I also have asterisk on same machine and I am able to connect softphone to asterisk.
