Established sSite to Site SSL VPN, Voip phones only working partially

Hello - I have an XGS 2100 at HQ. We were using a RED device to connect the branch office Phone and LAN traffic via VPN to the HQ PBX/LAN and everything worked fine. Given the rollout of the latest OS, the RED is no longer compatible, so we are attempting to repurpose an XG125 to a VPN client for the branch location. I successfully established the VPN effectively bridging the two LANs (HQ and Branch). I have confirmed that traffic is flowing between the two networks as I am able to ping, remote in, etc... with no issue. However,  the phone only works partially. I can make and receive phone calls but my audio does not go through, meaning someone can call me and they cannot hear me on the line despite me being able to hear them or vice versa. I have verified that traffic is flowing to and from the PBX but for some reason it doesn't want to work. Has anyone else tried to do something like this and ran into this issue?

Matt
