Unable to register softphones to FreePBX server

Hi All,

I’m a newbie to freepbx and very impressed so far with it’s interface and hoping to implement it in the office once I’ve familiarized myself with it.

The only problem is i’m getting an error of SIP error 503 on x-lite (Just using x-lite for testing before I purchase the phones).

I’ve checked the “Full” log and nothing is shown as bad password or anything.

i’ve then performed a wireshark trace and this is the output i’'m getting to the servers ip address:

what am I doing wrong please?

Many Thanks.
