Enable QOS on iax port


How can i enable qos on iax port.

I have a very bad voice quality on my IAX to IAX calls.
And sometimes caller from the outside could not hear us but we can hear them clearly.

Really need help, Thanks

you need traffic shaping setup on a device that is the single entry/exit point for all voice and data traffic in your network that will throttle back inbound and outbound traffic based on pre-set in/out bandwidth speeds.
