There has been much buzz of late about using IP telephony solutions in place of the more common analog based solutions. Traditional telephony has very high reliability (many years without loss of dial tone for some companies). From what I have seen in this group about networking, router behaviors, etc. it seems to me that the IP networks that exist aren't yet ready for the prime time of IP telephony. As we move buildings, my company is looking at installing an IP telephony based solution (packet switched) instead of a traditional analog based solution (circuit switched). I am worried that the reliability will likely be lower than I am used to. However the cost savings look quite compelling, so I am torn. The more I read in here about threats and attacks against IP networks and the amount of maintenance we need to have in place to keep our IP networks hanging together, the more I am concerned about the viability of an IP telephony solution. Does anyone here have any thoughts, experiences, etc. about the use of IP telephony in corporate environments? Thanks in advance Chris
