I am starting to think that the problem may be in the server hardware
itself. We are using a Dell R220 with 8gb of ram and 2 hard disks in a
Raid 1 configuration (Linux Raid). We are using CentOS 7. We had to
remove the raid card from the server to install an E1 card (the raid
card was Windows only so no loss there really). Internally everything
sounds good (from E1 to a conference or music) but once you hit a
network interface we start getting pops and drops.
Anyone with this server and Asterisk ever had issues like these?
