I want to use it to register against a proxy. I enter the command: sipsak -U -C sip:1234@192.168.0.5 -a password -s sip:1234@192.168.0.5 I get the message error: REGISTER Contact uri doesn't not contain sip:, *, or is not empty" If I enter the command sipsak -U -s sip:1234@192.168.0.5 -a password then the register message gets sent but with a contact of sip:1234@127.0.0.1 Could anyone help me with the correct syntax to use?
