I have used FreePBX for years and never had a problem but I really don’t know how to configure this trunk and I am sure it is easy to people who know so any help greatly appreciated.
I have purchased a number with AVOXI and then are forwarding the calls to my static IP address. There is no username or password and I have 3 IP addresses the call may come in from.
I have opened all three IP addresses through the router for 5060 and I have also set up the three IP addresses in the FreePBX Firewall as trusted.
I have the DNIS they are sending and the SIP signalling IP address.
I am sure it must be easy but I have always set up trunks with usernames, passwords and register strings so if someone can point me in the right direction I would really appreciate it.
