T46G Issues Save Volume settings + BLF pickup

[Jeroen]

Hello I have currently 2 issues with out T45G phones

Setting
- Firmware 28.72.188.13
- 3cx V12 PBX
- manual provisioning

1) I have configured some DSSKeys to have a blf. In the Extension field I put the default pickup code for 3cx (= *20* ) to be able to also pick the line up, but it does not seem to work.
It does dial the associated Extention, but it refuses to add the pickup code

2) I am looking for a way to save the Volume settings of the T46G. so that after a reboot, the ringtones are not to loud.

I searched the forum and Google, but could not find a solution yet.
Thanks in advance
