You may want to try out the Telephone Coupler TC-1  by Phonak.  
Any hearing aids with direct audio input  can  be interfaced wtih this
device. It's small and potable and the sound from the telephone is
directed into the hearing aids via a cord/audio shoe.

I have recommended to a client and he is very happy with it.

>My 7-year old son wears 2 Unitron US80 Sigma hearing aids.
>He has a bilateral severe-to-profound loss.
>I would like if possible for him to start learning to use the telephone.
>I know this is very difficult but I am hoping that with familiar people and
>simple conversation he can have some conversation.
>The problem is when we switch his hearing aids to the T-switch he says he 
>can't hear anything. The telephone is hearing-aid compatible. I listened
>to his aids using a stethoscope at the telephone and could hear someone's
>voice very faintly. I even tried moving all around to see if I could get
>a stronger reception.
>Is this as good as it will get? If so how does anyone use their T-coil?
>For the time being we push the "speakerphone" button and put the volume on
