I'm a newbie to kamailio. I have tried out installing kamailio server on my system to set up SIP server. I have configured POSTGRES sql as database. And I'm able to create required tables. [ INFO: Extra tables succesfully created.] . I hope I have configured kamailio server even correctly. I'm able to run SIP server but unable to add any user to it using kamctl. It always pops an error message saying [ INFO: user 'jojo' already exists as alias] . Its failing to add any user under sun with same error message saying already exists. But I dont find any user added. I'm nt able to understand the exact problem. It would be of great help if any one can give me pointer to solve this issue.
