Hey hi.
I have 10 SPA525G phones with me for which I have bought a CISCO 2911 ISR, But after configuring it up, the router says it does not support old model phones such as the 525G.
Any idea on how to install. Please help
I see discussion where people have already installed similar modules. And hence the question. Called up cisco, but they were helpless and asked me to buy new phones.
