How to increare phone book limit on Alcatel SP2502_v2

[fpgiuliano]

Hi to everyone!
i'm a new user and in my office we use Alcatel's SP2502_v2.
The phone are good but they offer a limit of 500 number on local Address book

Is it possible to change the phone configuration to accept at least 2000 numbers? I would like to avoid having to configure remote address books for company firewall problems

if yes, i need to connect to my phones with putty? i have already user and password
thanks to whoever wants to give me a hand


p.s. I hope I'm not in the wrong section to post this question (if yes, i'm very sorry)
