YeaLink T46G Tansfer to Prefix+BLF

[tsukraw]

So i have a customer who wants a Xfer VM button on there phones.
After doing all research i found there is a Prefix option for a DSSkey on the YeaLink phones.
I programmed a PreFix key as *4
If i press Prefix + BLF i go to the BLF extensions voicemail as expected....

However if i press Transfer + Prefix + BLF the caller gets transferred to (Please enter extension number and then press #) like it got sent to 99 instead of the voicemail of the extension....

Has anyone ran into this before or attempted it?
We are running 3CX V12 SP3
Yealink T46G running firmware 28.71.0.176

Thank you

Actually after a little closer looking at what happens when you press Transfer + Prefix + BLF. The phone is actually sending Transfer *4 it is missing the BLF number. Not sure if that helps anyone narrow down what i am doing wrong

I have attempted to use the prefix button as you have mentioned, unfortunately it seems that if there is no active call it prefixes just fine, but if there is an active call the prefix button sends the digits immediately. I have not found a way around this.

Wouldn't you say this is a bug with YeaLink since you get 2 different results depending on the state of the phone?

possibly, i did not investigate it that far as i was performing the testing more out of my own curiosity than trying to complete a request from one of my customers.
