I currently have a UC520 at the office with 3 phones and the pstn lines coming into it. I have two RV042 routers setup with a vpn between the office and my home. I cant get my phones to register with the UC520 from the house. Basicly i have a RV042 at each site with a VPN setup and I can ping vnc rdp etc into pc's from one site to another. I cant for the life of me figure out how to get the phones to register with the UC520 from the house to the office across the vpn. Is this the correct way of going about it? Should I just use one RV042 and VPN directly into the UC520? Can I leave the current VPN in place with the two RV042's and get the phones to work across the vpn to the uc520? Looking for some insite and help.
Thanks for your time.
