Does anyone have any experience running VoIP over such tunnels? Is there a technical reason why this solution is not feasible? Are Cisco routers not happy doing VoIP/IPsec/GRE in concert?
The company I'm working for uses Shoreline VoIP PBX gear spread out over maybe a dozen offices of varying sizes. All are interconnected through the corporate enterprise net, Cisco routers with IPSEC/GRE tunnels over the public Internet. Each office has at least a T1, and we use a variety of providers. We have a typical mix of enterprise interoffice traffic: email, web, file sharing, etc. There's no QoS configured in the routers at present. It all seems to just work fine. Steve
