[Asterisk-Users] SPA-3000 as FXO Gateway for * (Was: Qs aboutFXO/FXS cards)
Voxilla.com has a great config wizard for the SPA-3000 and * voxilla.com/spa3kasterisk.php I took the output from this wizard and dumped it on my test box with an SPA 3000 (with some mods to match my * contexts) and everything worked great. Calls from the PSTN to the spa3000 are routed to dialplan #8 on the spa3000, which dials * Both the FXO and FXS port register with * The SPA3000 is set up as a SIP peer in * with auth for outbound calls to the PSTN. Pretty cool for $100, a FXO and a FXS for * You need to play with the PSTN answer delay to eliminate extra rings on the caller side, but still allow the SPA3000 to pick up caller ID.> -----Original Message----- > From: asterisk-users-bounces@lists.digium.com > [mailto:asterisk-users-bounces@lists.digium.com] On Behalf Of > Damon Estep > Sent: Monday, January 03, 2005 7:42 AM > To: Asterisk Users Mailing List - Non-Commercial Discussion > Subject: RE: [Asterisk-Users] SPA-3000 as FXO Gateway for * > (Was: Qs aboutFXO/FXS cards) > > Thanks Rich, > > I have an SPA-3000 laying around, so I will attempt to set it > up in a little more conventional manner (although your method > looks like a winner for a home test PBX).
