I have a client with a BCM50 and 2 remote office one with one i2002 phone and the other with three i2002 phones, they are currently using 3com office connects with VPNs over adsl that crash all the time and take the phones out, can anyone recommend an adsl router with built in VPN for use with the ip phones, I know I can use cisco 837`s but I`m looking for a cheaper option..
