IP to IP voice call quality
Problem:
VN to VN or system related calls are of bad quality.
Solution:
VN to VN call quality depends entirely on the available bandwith the two communicating parties have.
Please check the following:
a. Contact your ISP to determine your Internet speed for upload and download.
b. If you have any other PCs or SIP adapters within your network, please unplug them from your
modem or router and try to place your calls again.
c Change the CODEC your SIP device is using. G729 and G723 are most low speed bandwidth friendly.
c. If using a softphone, make sure your PC has enough resources in order to run the softphone by reviewing the
softphone's manual. Check the available disk space and RAM memory.
d Some times having a peer to peer software like Kazaa or Lime Wire affects the performance of
your network since downloading files utilizes a great amount of bandwidth.
