If "fxo" means your SIP provider, and you register with him, a specific
extension will be called. Which one shall be called can be selected by
the last parameter of the register statement, e.g.

register => 075741:password at sip.provider.com:5060/492281234567

will cause the incoming calls to appear in extension 492281234567.

Comes in handy if you have several accounts with a single SIP provider:
This way, you can simply distinguish the outward phone number for which
the call came in.
