TLS Session Resumption Timer
TLS Session resumption enables a TLS session to resume without repeating the entire TLS authentication
process. It can significantly reduce the time taken for TLS connection to exchange data.
Although Cisco Unified IP Phones 8961, 9951, and 9971 support TLS sessions, all TLS sessions do not support
TLS resumption. The following list describes the different sessions and TLS resumption support:
•
TLS session for SIP signaling: supports resumption
•
HTTPs client: supports resumption
•
CAPF: supports resumption
•
TVS: supports resumption
•
EAP-TLS: does not support resumption
•
EAP-FAST: does not support resumption
•
VPN client: does not support resumption
