We are installing the ASA Phone Proxy for use with about 150 remote teleworker phones. It is my understanding that the licensing is done on a per session basis. Does this per session basis refer sessions established by the phone to the ASA or from the phone to the CUCM servers. Meaning, will we need to purchase a license for each phone to call manager server session?
So if i have 150 phones and 3 call manager servers will i need to purchase 450 session licenses?
