Hi there,
all that started by investigating what happens if SIP clients are calling anonymously.
The problem: Every client who is registered as a regular user with username and secret can fake any callerid in subsequent INVITEs. Asterisk does not apply an accountcode or callerid from sip.conf. Those calls end up unbilled and untraceable.
Is there any way to fix this problem - did I misunderstand something, what am I doing wrong?
callerid=Anonymous User <5556667777> in [general] in sip.conf.
A better way would be to set context=INVALID (or some other not valid context). Then make sure each client has context=something in their [happysipclient] section.
Create a sip.conf entry: [guest] context=something callerid=Anonymous User <5556667777> disallow=all allow=gsm
