networking - VOIP and internet connection speeds [cable vs. fiber]



Our office is migrating to IP telephony. We have less than 10 employees that will be using the phones. We currently have cable internet, and they just bumped the speeds:

There is a data center that was just recently built in our building, and we were considering co-lo'ing there in the near future. As a result, they offered us access to their triple-redundant internet, but it's quite expensive. They are offering 3mbps committed with up to 10mbps burst for $250/month (discounted). We pay ~$120 for our cable (which the plan was to keep--at least for TV).




I want the phone system and LAN to be as separate as possible. Was thinking about keeping the cable for LAN, and using the other connection for the phones (until I saw the price). Now I'm thinking it might make sense to add on to our existing cable setup, and change our phone to only have DSL as a backup for the cable.



Is there any real benefit to the fiber? Especially for the price? Any other suggestions or ideas?



Thanks.


Answer



Yes there is benefit for fiber...low latency.



VoIP is prone to problems with Jitter (latency). You'll have low volume issues, dropped calls and noise on the line.




Although to support 10 users I'm not sure if you really need the fiber. Especially if you add QoS on your network...and that is a must if you do VoIP.



Lets say I would consider it a very nice to have.
