I hope someone can tell me answer, because I spent a lot of hours finding answer on google, but no success.
I have this scenario.
Internet > asterisk pbx > VOIP provider
I was wondering if it’s possible to use kamilio for a additional security in registration SIP phones outside local network.
Internet > kamilio proxy > asterisk pbx > voip provider
I want that the user will have to register with two different passwords.
 type=friend context=company_internal username=218 secret=112ddsaas nat=yes host=dynamic
AND with sip proxy with additional user name and password.
I need this because we already had once hack in our asterisk system.
Thanks for any additional information.
