IP Phone with the highest number of programmable keys

Hello,

I’m looking for any suggestion about the IP phone that have the highest number of programmable keys also supporting BLF.

For the moment, the higher is 7 keys for the Aastra 9133i. I’m aware about the Polycom IP601 with an expension module but this solution is too much expensive. About 325$ CAN for the phone and 250$ for the expension module.

Thx for your suggestion !
