MJ+ won't recognize Google Voice DTMF buttons

[culeboards]

From my MJ+ phone, I dial my Google Voice # to access my GV messages and to place calls to Canada by pushing #2 (or changing settings by pushing #4), etc...

I can no longer make the call via my MJ+ system as GV is not 'hearing' the button being pushed.

Works fine from my cell phone (which I would rather not use for long calls to Canada).

Anyone else experiencing this issue? It used to work fine and nothing has really changed.

I plug my MJ+ into the wall and have a Motorolla modem SB5101N.
Frustrated again with MJ.

Most grateful for any help.
