If the phone registers and you can see it online, then I expect it is not a problem with the firewall. What happens if you try to dial the phone from the office? does it ring but same one-way audio?

Check and see what IP range the VPN is assigning to the phone. Usually when this problem comes up we find that the VPN is configured to hand out some other local address range (i.e. LAN is 192.168.1.0, but VPN is 192.168.5.0 etc). In Asterisk, check to make sure that the VPN address range (if different from LAN) is configured under the "Local Networks" SIP settings. That most likely is the heart of the problem.

thank you!
