Putting caller on hold from an analog phone

Does anyone know the shortcut key to put someone on hold from an analog phone. I have a handytone-286 connected to an anlog phone and I would like to put calls on hold. However, I don’t know if there is a feature you can access to enable that. You can transfer by pressing #, however, I don’t know if the hold feature is available. Appreciate a response :question: :question:


Flash gives you another line and gives the call music on hold. However, I would like to be able to just put the user on hold. Is that possible?
