Slowly getting things working. My next challenge - can anybody point me in the right direction on how I will accomplish this? My goal is to have the customer’s phone on his internet connection, logged in to my PBX.
My PBX is on my internal network, which is protected by an ASA firewall. I use port address translation at the firewall to control traffic that’s allowed in. Obviously I’ll need to allow UDP 5060 in. A problem that I foresee is the wide range of ports that FreePBX uses; I believe it was 10000 - 30000. My firewall (ASA5505) doesn’t allow me to specify that wide of a range. Are there any other options here? Also should I configure the phone internally first and then deploy, or should the client be able to configure at his home office?
