Ooma hub is set up between Comcast modem and a Netgear router. QOS in router is disabled. Am currently using Comcast's Digital Voice service, so phone line from Comcast modem goes into to Ooma, then from Ooma goes to jack that provides service to the rest of the house. (Don't ask. Reworking of very old phone wiring in very old house. But system is very functional.) If Ooma works well, will port number to Ooma and cancel Digital Voice.
There is slight delay in phone conversations. Just enough to be distracting. I would guess approx. .5 second or a bit more from time one person begins speaking until it is heard by person on the other end. Sometimes delay is closer to 1 sec. Echo is very limited, although occasionally detectable. Sound quality otherwise quite good. Detecting no hesitations, gaps in sound, etc.
Any suggestions to help me reduce this delay in sound transmission?

Do you experience delay when you place an outbound long distance call with ooma (e.g. you dial a long distance number and carry out a conversation)?
I am thinking that if local calls that are going through your existing VoIP connection might be causing the delay.
Open pingplotter and use some address such as http://www.cnn.com ...etc. and notice the ping times from you to them. If it is consistantly over 100ms in router-hops, something is wrong and the cable company may need to be alerted.

I have a 700kbs upload speed and 1.5Mbps download speed. The DSL modem is connected directly to a router. The Ooma box is connected to the router. Also connected to the router is a Vonage box. The Vonage system does not suffer from this issue. Both boxes are NOT run at the same time. No other internet loading is occurring.
It would help to know more information. Run a test here: http://www.whichvoip.com/voip/speed_test/ppspeed.html and post your results in the text format back on this thread.
