SPA122 QoS doesn't work

[parseINT32]

i'm currently using my spa122 as router, the calls are always lagging, i can't understand any single word of who i'm calling.

If i'm calling and while i try to ping google.com the packet loss increases up to 80%

I've an ADSL connection with 512kbps in upload

If i set this value in qos settings the call quality is poor, while if i set it to a number bigger than 5000 the call become to be normal

I have problem with QoS SPA 122 too. I have a Cable modem. Internet connection is 7 Mbs down/ 250 kbs up. SPA 122 is plugged directly into my cable modem. My PC is plugged into the SPA122 - which is working in a router mode.  When I am not using internet calls are cristal clear. When internet is in use words are getting cut off or lost. Upload or transmission seems to be the biggest problem. People can not hear me well. It is worse with higher QoS upload speed settings. It somehow works betterw ith lower values (160-190) kbs- but - far from perfect. BUT - at those low settings my download speeds are getting severly restricted as well - to about 160 kbs down.
