I have 1MB wireless link from my ISP. I am using Cisco VOIP phones in my company. Over the months my VOIP quality is not good(on/off connectivity),though my internet is somehow working fine. When I talked to my ISP , they told me to use Cisco switch / router instead of Nortal. Moreover ISP also saying that the switch / router can be configured to full duplex/ half duplex because ISP equipment can be switched to half/duplex.
1-what cisco router/switch should I use with voip phones ?
2-What duplex setting should be on the router/switch so voip quality be remains optimum.
3-Is 1MB link can be used for voip?
4-Is it possible to configure voip phones to full/half duplex ?
Please help. Thanks.
