IP Office IP phones

[Howardf77]

Hi,

I am installing a new IP office with 5 IP phones at 2 other sites. When I agreed to the system I was told that the IP phones will work fine. I have pinged computers at each site and I am getting about 120ms response from them, will the phones work ok?

Any comments would be great.

Before deploying ANY multi-site VoIP it is recommended (and should be mandatory IMHO) to have a network assessment completed. There are several flavors of this, Avaya has a list of approved methods and software but anything that measures delay, jitter, out-of-order and QoS enforcement will let you know if your network will handle VoIP.

Network assessments are indeed recommended. But a ping delay isn't always going to tell you how your voice quality is. Chances are the phones will work. Will they work well? Hard to tell, and your best bet is to just plug a phone in and see how it is if you don't have the resources to run a full network assessments. There are a lot more things that effect voice quality than just delay.

120 is high but as the guys say ping is no way to test voip. What Qos is in place, what bandwidth is available, etc.... 2 sites with 5 phones in total shouldn't really be a problem but how many calls at any one time? Set the codec to G729 and see how you get on. there are proper voip rtp testers available but maybe a case for plug and pray.
