We are looking to implement a Mitel VOIP soloution at my company.  I 
have one of these: http://www.synertrontech.com/light.htm at each 
location running ipcop, they all have 128mb flash cards and 128 mb ram 
(yes overkill but wanted to leave options open).  They are running at 
533 mhz, the one at our main office is running 1Ghz with twice the ram 
and cf storage.

I need to proritize the VOIP traffic, ie traffic shaping and I need 
ipsec vpn capabilities.  I know monowall has the options to do both of 
these.  I haven't tried the traffic shaping, but I have tried the vpn 
with monowall at my house connecting to ipcop at work.  My vpn 
connection seemed to require a ping once a day to keep it up.  Is that a 
ipcop monowall connectivity problem?  Has anyone had any experience with 
implementing a VOIP solution other then a home voip system like vonage 
that included monowall?  Any comments would be most helpful.
