Cisco Webex Calling - One way calling

L0 Member

Does anyone utilize Cisco Webex Calling with a Palo Alto firewall? We run Webex calling and ever since we switched to the palo alto, calls sometimes will only go in one direction (you can hear them, they cant hear you) or no way (either sides cant hear eachother). I reverted back to PAN-OS 9.1.1 hoping that would resolve the issue but the issue still occurs

Are you decrypting the traffic? If yes, try bypassing decryption for it. Also check the logs to see if anything is getting blocked between the devices.
