Change vlan setting to more than one phone at once

[xrpapak]

I have about 90 phones and I need to enable vlan for both PC and WAN ports. I have configure my HP switch ports for access and voice vlan needed and now I have to setup the phones.

However, about 90 phones are too many to change them manually. As a result, I should find a way to make the change I would say "automatically". Firstly, I thought of a script which would export the configuration file of each phone, make the changes for vlan settings, import the file and reboot it. The only method I thought if this could be done is via http post but I have difficulty in implementing export and import of the file.

Could someone give me a hint with this? Or maybe is there another way to implement the scenario I mentioned?

Thanks in advance.
