Old 2.20 version disable button, if example extension not have mobile number or voicemail in buttons.cfg. New 2.25 version not. Whats the problem?

We have 3 lisences, one fop is version 2.20 and two 2.25. All asterisk servers is same versions and same configs.

buttons.cfg (example)

[SIP/1111]
type=extension
extension=1111
context=default
label=Test
mailbox=1111@default
privacy=clid
queuecontext=Testi
<!-- e --><a href="mailto:email=[email protected]">email=[email protected]</a><!-- e -->
external=001234567@default
group=test

i read english better than write :D

for example, if person doesnt have cellphone set in config, it should disable 'transfer external' button when that person is selected, but it doesnt disable it in 2.25

clean installation, debian 32 bit works ok, 64 bit not.

All version works. Problem is user permissions in fop.cfg.

work:
user=1234:1234:all

example not work:
user=1234:1234:dial,hangup,pickup,transfer,transferexternal

next problem: how i hide example "spy" button?

it only works when user has all permissions. I only want to disable(not hide) it when selected user doesnt have cellphone number set in config.

yes
