Thanks in advance for your help. I've been tasked do the following and wanted your suggestions:
We have 2 locations, New York and Florida. We have 2811 routers with a T1 data connection from ATT for both sites. We will be installing a Call manager at the New York site and having the 2811 perform SRST at the Florida site.
We are doing NAT for both sites, so I wanted to ask what would be the best VPN method for Site to Site connection for VOIP and data, while also allowing the users to connect to the internet via the ATT T1. I will also need the ability to have remote workers connect via software VPN clients to both sites and be able to run IP Communicator. Would a regular Site to Site VPN tunnel with IPSEC work, or will I have to look into setting it up with GRE for the VOIP to work properly?
Thanks again for your help!
