We have cuts in VoIP. We have MX64 and MX84 in our offices. We have Cisco Call Manager. We suffer a lot of cuts in calls, provider that configure Call Manager has testing all and they have found a lot of icmp traffic from all MXs to Call Manager.
I have a doubt, is it a normal behavior that MXs send a lot of icmp traffic against Call Manager servers?
Check out my video on building high quality VoIP rules in the MX. Also in each MX, go to SD WAN & traffic shaping and add the public facing IP of your call manager server to check if packet loss is happening on the ISP WAN side.
