I am facing problems with audio delay when answering phone calls. Sometimes, when we receive a phone call, even after picking up the phone the other person still hears ringback.
After around 7 sec, the call gets connected. Once the call is connected,
there is no audio delay. It happens only when the bandwidth usage on the WAN
link is high.
Is it a "QOS" issue and if so then how to rectify the issue?
Could someone help me on this.
I am attaching the running config.
