Is Freeswitch terminating the call as well? Or media flows between IP Phone and external SIP Trunk. Cisco Phones offer your CDR/CMR records which give you a good detail in terms of Media statistics. If using CUCM you need to enable it in Service Parameters. You need to isolate it to: 1. Device, device firmware 2. Location 3. Time of the day when this happens. 4. Check all network path ( IP Phone -> Access switch -> Core switch -> Router -> Public Router -> Internet...) etc. 5. Validate correct NIC settings (speed) and LAN QoS. 6. Etc...
