Guys.. We havent even started taking about costs here. Velieve me, this
customer is not concerned about costs ... At least not yet... He just wants
to know if there are any IS wifi phones compatible with asterisk out there.

You are thinking too fast too soon..

|Thanks Dean, I was trying to communicate this to him also. I 
|manage IT/IS/Comms for an Oil company[1] and we have equipment 
|installed at our refinery and at our drillsites.
|
|IS is a fundamental building block of all our work, and yes it 
|does increse the cost by a factor of at least 3 and more 
|likely 10 when all the other costs are taken in to account.
