first please see the file attached
its a quote from my consultant.
i have to change all my telephony system to voip. and honestly i dont know so much about this technology (voip).
my question is, in the file, is it normal than some lines dont have a price? these lines are included with the cisco2811 or in additional modules ?
-cisco unity express base release - 3.0
-cisco 2800 SP services
-Device manager for routers
thanks for those who will reply.
