VoIP over VPN dropping daily
Posted on 2006-06-05
Our office has recently installed a Comdial MP5000 phone system with the intentions of distributing CONVERSip EP300 SIP Endpoint phones to several of our remote branches to, of course, use the VoIP features. The problem is that I have sent two of these phones out after finally getting them to work and they are dropping the VPN tunnel constantly and phones are crucial to our business.
Here is the current network layout:
Office: Full T1 -> Netgear FVS318v3 -> Comdial MP5000
Remote Sites: DSL (768k up/down) -> Netgear FVS318v3 -> CONVERSip EP300
I understand that the Netgear routers aren't the most reliable things ever. When I began to set this all up however, I was informed that it wasn't a huge deal considering that at most I would have 6 outside phones. Does anyone know of any specific settings I need to look at to get this thing up and running for more than one day at a time? If a change of equipment is necessary, any suggestions? I see a wide array of high-end VPN routers but if I am going to have to justify spending roughly 4-5x of what I originally did I need to make sure they are flawless.
Thanks in advance.
