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" http://www.cisco.com/en/US/tech/tk652/tk701/technologies_tech_note09186a0080477a06.shtml -- Joseph _______________________________________________ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- AstriCon 2009 - October 13 - 15 Phoenix, Arizona Register Now: http://www.astricon.net asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
