Has anyone tried the Flying Voice IP phones? They offer a version with 20 BLF buttons. So many people in small businesses are moving from systems with a large # of BLF buttons and don’t want a replacement with just four or six buttons. But there don’t seem to be a lot of choices out there either for SIP phones with a large # of buttons.
To find the phones, you can google “Flying voice IP652” or here is a link (if the forum allows me to post it):
