Yes, thanks. I do read Asterisk News. It's a good source of info! :)

I'll give it a try sometime soon. These Nokias 32 do have the option of 
reversing polarity for X ms to indicate a call is connected or they can 
reverse polarity for the duration of the call.

It's nice to see development is being done in zaptel.
