t46 versus t48

[troosters]

Hello, I have 4 questions regarding yealinks and 3cx :

1.
If I make a call with 3cxphone the T46 puts the call on hold while it is dialing the destination number.

If I do the same on a T48 it does not place the call on Hold on the callers side, but you hear it ringing ?

is there a way to do that as well on a T46 and T41 ?

2.
Also the 3cx logo on the T48 blocks the view when showing all BLF keys. If I would use the default logo this would be the Yealink logo. But I guess it will be the same issue.
How can I turn off the logo in the provisioning template at all ?

3.
If I want to dial the cellphone of a extension instead of the extension. Is there a way to do this on the Phone ? Or can I only create a new extension for only the cellphone number ??

4.
On a T41 , when you do a transfer the remote phonebook is not automatically available, only the remote one.
Where in the provisioning template can I change this ?
