Trying to set up a asterisk system for my office network with limited Network experience, and some asterisk knowledge.
I currently have the * box on a private ip address and it works perfect inside using polycom phones and sip. Of course I want my 2 remote users and their polycoms to be able to use the * box as their phone switch too and I am experiencing the typical problems of one-way audio, not being able to route calls to destination etc etc - all normal SIP problems.
I have read a fair bit on the internet about stun, IP tunnelling and am not really too up to speed about all of these, and there seems to be so many different solutions out there to this problem.
Does anyone have a known setup for remote users with the * box being on a private ip address that works? Do you need to use STUN and IP tunnelling or can this just be setup with changes to the firewall and config files?
