I have a site in London that has Cisco VOIP running off a 2811. We have a VPN tunnel up and running. I have a 2811 that some else started to config. Is there a link that would show me how to configure the other 2811 correctly. This going to be a test. Any help would be appreciated.

It will work but It's not recommended with 2811. Although VPNs guarantee a secure pipe end-to-end, they don't guarantee latency and variations in latency (Jitter). Therefore, the voice quality will likely suffer, depending on traffic conditions on the 'net.

hi Spencer
i can see from the files u have attached that u have a CME and u may look to let users in a remote site to rigister with that cme
based on ur requiremnt u will need basicly normal VPN between those router
but u need to conisder the ports that involved in the VOIP,and IP telephony to let t he phones rigister and voip flow over vpn
the following link is a case similer to yours but it include a firewall setup
igonre the firewall but consider the ideas like ip source and destination and PORTS :
good luck
