I have a couple of ES3500 25HP series switches. They are in two different networks. One has firmware V4.00(AADE.3) | 12/23/2013. The other is older. I cannot log into it at the moment to check. Anyway, I have these switches on a VoIP network with Aastra phones and an Asterisk based server. In one location I have an Asus RTN16 router running DDWRT-2.4 mini, connected to a Cable connection. The cable testing at the modem is approx 60 / 4. Running the same test at the switch is 4 / .5 The other location has a Sonicwall connected to a cable connection at 100 / 10. The test behind the Zyxel is the same. I have DSCP set to 0 for 24 & 46 in order to provide QoS for the phone system. There is little else configured except PoE on as needed for the ports. Can anyone comment as to why I would see this much difference in the testing I did for internet speeds? I have been having call quality issues at both these sites and now I am starting to doubt these switches.
Thanks for any ideas.
