I have managed to connect to Asterisk server together. Now extensions from one side can call the other. Using SIP. For some reason though, I am unable to hear any sound from the phones connected to the same server. I also cannot hear the voicemail prompts on the server, but do see that the voicemail is working and when entering in the login info that works too. I just don’t hear anything.
I am running these systems on an isolated LAN with no firewalls (if this information helps).
I am new to Asterisk so please let me know if there is any other information that is required.
