Hi I have installed elastix 1.6 latest stable 32bit version on a rhino 1u server. I have 10 polycom ip650 phones with the expansion modules. The server is behind a Linksys RVL200 router all proper ports are forwarded to the elastix box. Phones can receive and make outgoing calls but every now and then the call fades in and out. The internet provider is time warner cable with static ip. Speed is 15 mb down and 2mb up. There is no heavy downloading or uploading at all. what could be causing this problem? The latency between the server and the voip provider is 10ms the most it ever hit is 45ms. I use the same voip provider for other locations and there is no fading in or out. Please help, thanks in advance.
