[asterisk-users] Receiving SIP calls without registeration and dynamic IP address

[bilal ghayyad]

Hi List;

How can I configure asterisk to receive a call from
SIP end point without being registered at asterisk and
its IP address is dynamic, and authentication to be
based on the username and password or any other
string?

I know that if I place the host with static IP then no
need to register, but what if the voip gateway was
having dynamic IP and I do not need to register on
asterisk, but I need to send the call directly and
asterisk authenticate the device based on the username
and password or any possible string?

Regards,
