Apologies ahead of time but my Google skills appear to be failing me today but I just cannot seem to find a clear answer on this.
Let’s say we have two extensions (extensions 21 and 22 for instance) in a remote office that connects through the office’s site to site VPN tunnel back to the main office’s FreePBX box. If extension 21 wanted to call extension 22, how much of that traffic for the call would need to go over the VPN? My guess would be the SIP portions would have to go to the FreePBX box but the RTP traffic would go between the two phones.
Thanks in advance!
