[cisco-voip] VoIP Deployment Questions

[Carter, Bill]

In designs like this we like to us Qwest.  Qwest is able to work with use on latency guarantees.  Are you talking with them?

Subject: [cisco-voip] VoIP Deployment Questions


Hi all.  I am in need of some guidance regarding uptime, packet loss and
latency for national / international VoIP network.  We will be rolling out a
VoIP network.  The first phase of the deployment will consist of getting the
customer HQ located in Boca Raton, Fl. and one of the remote offices located
in Los Angeles.  LA will have a fractional T1 to the local POP and Boca will
have a full T1 at the main office to the local POP.  We will have VPNs
between the remote offices and the HQ.  Future deployment will also include
New York and London.  All packets (voice and data) will leave the network in
either location as a standard IP packet.  I am in the process of looking at
a few different carriers and selecting one for this national / International
VoIP rollout. QoS end-to-end is a big concern for me.

One of the carriers I am looking claims that it guarantees a 99.97% uptime
and no more than .05% packet loss during any calendar month.  However they
do not offer QoS.  

Is this consider acceptable for a VoIP deployment?  What sort of uptime and
latency and packet loss should I be looking for?  Would you still require
QoS if the network utilization of the carrier is half of its capacity?

Any recommendations for carriers?


Thanks.
