Source note · Webex Calling ICE media path optimization
Cisco states that where STUN and ICE negotiation succeeds for a call within the organisation the media relay in the cloud is removed from the communication path and media flows directly between the apps and devices, with the Webex App sending directly on 8500 to 8699 and devices sending directly to one another on 19560 to 19661.
