Dear NetPro gurus,
One of my customer has recently upgraded their CUCM from 8.0 to 8.5. However, after the upgrade, we still can't find the VPN configuration settings on the LED screens of their 9971 phones.
Does anyone know how to activate the VPN Phone features for 9971??
CUCM ver:- 18.104.22.16800-26
9971 Phone Load:- sip9971.9-1-1SR1
I have spent a lot of time on this already but couldn't get anywhere, would be great if anyone can shed some light on this.
