We are looking for implementation of Cisco IP solution. We have 3\nlocations to connect through it.\nEach location would have gateway to PSTN (60 lines) and about 250\ntelephones.\n\nWe got a tender for Cisco voip solution, the one with central 4050\nswitch and second with using our 3640 router.\n\nCan somebody tell me for pro/cons of using one way?\nHow it is with voip in general, does it really work so good, what are\nthe main problems?\nWhat should we be aware of and of what should we specially take care?\n\nThx . . . .
