I have external SIP gateways / trunks with no username/password that I want to add in to Digium but can’t seem to figure out how. I want to add these SIP gateways so I can send/receive calls to/from them using extensions. Has anyone set up something like this or know if there is documentation for it? I looked at adding them as a SIP Provider but it won’t register as these gateways don’t require a username or password.
I am also looking for a way to create an extension for my queues that can be accessed externally. Such that these SIP gateways can call these extensions and have their call be dropped in to the queue.
Thanks in advance.
