Hi All,
Customer has few phones which gets registered over VPN on CUCM 11.5. All VPN related configuration was correct on CUCM. Everything was working fine till now.
But, today firewall team have installed public CA signed certificate on the ASA Firewall. After that VPN Phones are not getting register back to CUCM.
What changes we need to do on CUCM side from certificate perspective so that phones will get register back to CUCM.
