I have an SPA232 with a couple of SPA302 handsets. I want to add the blind transfer and remove the regular transfer.
I found the setting (Blind Attn-Xfer Enable) in the 232's web admin and enabled it. After doing a firmware update the handsets picked up the setting and blind transfer is now enabled.
I am not sure if the regular transfer can be disabled, but there is a setting under Supplementary Service Subscription called Attn Transfer Serv that I tried to turn off. The handsets never changed. I wasn't sure if setting that to 'no' did anything or if the handset just hadn't picked up the change. So I reverted that change, and I turned Blind Attn-Xfer Enable back to 'no'.
Now the handset won't remove the blind transfer setting. I have turned the handset off and on. I have unregistered and reregistered the handset to the 232. I have factory reset the handset. I have rebooted the 232. Nothing I do seems to force the settings to apply to the handset.
So I have two questions.
1) how can you make settings apply immediately?
2) how can you remove the regular transfer from the handset?
