Hi all! We are testing the free version of 3cx and considering to buying the full version. I found it easy to install compared to my Linksys hardware IP telephone central. I just godt one huge issue! When I talk to my costumers I got lot of voice delay, when I say something in the phone it take about 3-4 secounds before the person in the other end receives it, in that time the person could have started to talk about something new - because af that I get some wird concersations. Besides that my voice also lags, it's also makes it very hard to understand what I am saying. I'm using QoS on my 3CX server. And i'm using Linksys SPA941 IP phone. At my VOIP getway settings in 3CX i'm using the lowest codec; iLBC I'm using the Danish VOIP providor named Redspot, and when i'm typing my VOIP proxy directly into my ip Phone I don't got any problems at all. The lag and delay only occours when i'm talking through the 3CX system. I got 8000/768 kbit/s connection - My VOIP providor, Redspot saying that the iLBC codec only reqiures 30kbit/s. My 3CX server is a Virtual XP client, running on a 3,0 GHZ intel Xeon, with 2048mb ram dedicated. When I call someone internal it's also take about 10 secounds before the internal Phone starts ringing, but when the internal call are stated i Dont got any delay or lagging voice. What do I do to stop the lagging voice and the voice delay under conversations?? And what do i do to make internal call's ring alot faster? Regards Frederiksen, Denmark.
