Hi,
I am a newbie to asterisk. I went through the wiki and other documents but couldn’t find any answer for how to register a user without creating any account in the sip.conf file. Can I register an endpoint to Asterisk without having a section in the sip.conf file for that user?
You can use allowguest to allow you to make calls without having a sip.conf entry, but you will not be able to deliver calls to that line.
Remember that, if you can make calls without registering, the large number of telephone fraudsters can also make them, so you had better have a good firewall, or be sure that you cannot make chargeable calls.
