VOIP not working over site to site vpn

Hey there
Changed public IP address on a TZ400 (sub office) and a TZ600 (Main Office)
Main office phones are working but since the change, sub office can hear the phone ringing but cant answer the call. They also cant make internal or external calls from the sub office. Wouldnt be too handy at the packet capture end of things
What do i need to check?

It is not a good idea to send VOIP traffic over a VPN. You havent given us much info to work with. Is the PBX in house at the Main Office?
