New install, Asterisk, obviously, Baystack 450 swtiches, verizon T1, Digium 4 port T1 card Some (few) users have had complaints from their clients that sound quality is poor. I do not know if the calls were placed via asterisk, or received via asterisk. If it matters. I believe this is a "QoS" issue, for the swtiches/infrastructure, wondering what can be done, if any one is familiar with these switches. If they are dog for Voip, recommendations? joe a.
