SIP Phone Registration


I have installed the Asterisk on Ubuntu on my system. When I am trying to register the 1000 user through softphone from same system it will give me the following error.

Sat 12:15:48
1001, registration failed: 408 Request Timeout

Sat 12:15:52
1001, fetching registrations failed: 408 Request Timeout

If, I register the sofphone from other pc for 1000, than it will work. But, when I start the sofphone on same Asterisk Server than it not able to register.

Can you please help me out, what configuration I have to change in sip.conf to work softphone on same asterisk server.

Thanks in advance


There might be port issue. Perhaps you softphone is using port 5060. Can you try and change the SIP Port in your softphone ?
