Need More Time for Transfer/Blind Transfer

Our school receptionist needs more time to perform transfers -

She uses ## to transfer but needs to hit those in rapid succession or it will fail.
Then, to transfer directo to voicemail she needs to dial *123 but if she doesn’t do it quickly, she’ll get the message “no such extension”

She’s older - so her fingers don’t move as fast as mine - I’ve searched but can’t find a way to give her more time to hit those sequences - can someone point me to the setting?

Does the phone have a built in transfer button? Those normally will work better and allow for more time.

It does but it seems to be programmed to do an attended transfer which is confusing for her.

What kind of phone is it?

You might be able to do it by creating features_general_custom.conf and populating it with:

transferdigittimeout => 3      ; Number of seconds to wait between digits when transferring a call
                                ; (default is 3 seconds). If the TRANSFER_EXTEN dialplan variable has been set
                                ; on the channel of the user that is invoking the transfer feature, then
                                ; this option is not used as the user is transferred directly to the extension
                                ; specified by TRANSFER_EXTEN (the transfer context remains the context specified
                                ; by TRANSFER_CONTEXT, if set, and otherwise the default context).
featuredigittimeout = 1000     ; Max time (ms) between digits for
                                ; feature activation  (default is 1000 ms)

replacing 3 and 1000, by suitably larger values.

However I haven’t tried this and don’t know whether this file is processed in a way in which the last value wins.

I am surprised that a receptionist is not familiar with attended transfers. On most phones, you can make them effectively blind by completing the transfer whilst the phone is ringing.
