This is how you can route out an incoming call out of the gateway. Let suppose the mainlineContinue reading “Hair-pinning Or redirecting a call from Gateway”

Scenario#34 – Cannot make International Calls from US gateway

Applying QoS for Voice Traffic

QoS is very important for Voice traffic which is delay sensitive. I won’t go into details of QoS over here and will just explain the configuration we normally use on a Voice gateway for QoS. class-map match-any Voice-RTP match ip precedence 5 match ip dscp ef match ip rtp 16384 16383 class-map match-any Voice-Cntl matchContinue reading “Applying QoS for Voice Traffic”
