Asterisk SIP register

The register directive (in sip.conf) tells Asterisk to register itself to a SIP provider.

The basic format for register is:

register => user[:secret[:authuser]]@host[:port][/extension]

If no extension is given, the ‘s’ extension is used. The extension needs to be defined in extensions.conf to be able to accept calls from this SIP provider.

The register statement must appear in the [general] section of the sip.conf file. If it is not in the general section then it will be ignored, and no error messages will appear.
