I have an Avaya S8300/G350 server (Communication manager v3)which currently has 4625 IP phones attached. We have purchased 9640 IP phones to replace the 4625IP. Please advise what configuration I need to make to the server i.e. do I have to open any ports etc. Also I understand that to make changes to the phone setting or upgrade its firmware I need to install a HTTP server. I have downloaded Apache but I am not sure how to configure it.
Please advise. Thank you.
