Cisco IP Phone Anyconnect SSL VPN Drops

[patrick.hurley]

I have been using a Cisco ASA 5505 for 10 years with a Cisco phone running any connect SSL VPN client. I switched to a Fortinet Firewall l and once a day the SSL VPN drops and the phone is no longer registered and I have to reconnect manually.  

Has anyone else seen this?

My guess is this is triggered by the key-rollover that occurs periodically, often this timer is set once every day

and this key-rollover may have happened more fluent with the ASA then using the Fortinet

[patrick.hurley]

What do you mean by more fluent?

without interruption
