I'm using RentPBX with OpenVPN installed on the same server. The Yealink phones seem to 'talk' over the public IP of their host rather than only using the private VPN IP - I'll eventually figure that out.
I have configured 2 iPhones running OpenVPN and Zoiper (free version). The VPN connects and the phones register. If either phone talks to a Yealink extension, the connection is fine. If the cell extensions call each other I have one way audio.
Phones are configured with NAT=YES in freepbx, connecting over 10.11.12.1 and Zoiper doesn't have too many options that would seem to touch the problem.
Has anyone seen a problem like this before?
