Thanks for the input, I'll try play with Linksys units.
The Asterisk on the other end has no Internet connection so I need to use PSTN line.
One thing I've noticed on the other end there is a bit echo and TDMF tones playing a bit loud when pressing the buttons, it it PSTN to SPA Gain or SPA to 
PSTN
Impedance is set to standard 600 but I'll try 900; but I've read from some sources that to find the correct match can be a "black art"
