I have a customer who has a SIP PBX in their main office and are connecting to their branch offices via VPN. The main site has a USG 50 and the branches use the USG 20.
The phones connect to the PBX over the VPN. I do not manage their network, but I do know they also RDP into a terminal server and access a file server. What is the best way to set up each VPN? Does it matter, performance wise, if I choose 3DES over AES? SHA over MD5? etc
Each site has plenty of bandwidth up and down. (all sites have at least 75mbps/20mbps_)
