Jan 15, 2020
- Cisco Telepresence Integrator C Series
Known Affected Releases
Symptom: Some work was made and integrated as of CE9.3.0 in which EPs will send a STUN packet when setting up media. Looks like this change has not been properly documented. Conditions: Customers who have a setup like (Endpoint >> RTP >> Firewall VPN >> RTP >> Endpoint) may have media issues when upgrading from CE8.x to CE9.3.x if STUN is not properly enabled in FW.
