[Freeswitch-users] Registration Error - 408 timeout

Hello Please pardon me if the solution to this is somewhere already that I have been unable to locate. I have just got a straight out-of-the-box build of FS. According to the wiki, I should be able to test using user IDs 1001 and 1002. However, I am get the above error. If I, however, un-tick register with domain I do net get the error but does not communicate either. Is there a conf that I should have done ? I am using X-lite3 Thanks in advance. Abeka
