T21P E2 attended transfer caller id name in history

[gralech]

Hi everyone!

I'm writing provision configs for our office telephones Yealink T21P E2
Everything working fine, except one thing:

After attended call transfer
A(calling, ex 7778899) -> B(secretary) -> C
on phone C caller id printed as "Secretary 7778899"

After call end on telephone C i go in History, and see: Secretary (w/o number)
if i go to history details for this call, i see number: 7778899

How should i change my config files, so after attended transfer on telephone C will be only number 7778899 (w/o "secretary"), and in history there will be only number 7778899 ?

Somehow i did this once, and now i can't find correct set of config parameters...

my config (selected parts):
y000000000052.cfg
features.save_init_num_to_history.enable = 0

<mac>.cfg
account.1.refresh_remote_id.enable = 1
account.1.cid_source = 4
account.1.cp_source = 0
account.1.transfer_refer_to_contact_header.enable = 1


Any advice?
