Oddly enough, I don't see any options in the Adit 600 manual for setting the codec for the normal FXS cards, but for the FXS5G card it has varying impedance settings. >From page 5-154 in the Adit 600 Release 3.2 manual Index 1, 120 ohms + (.110uf || 820 ohms) A-law Norway. Index 6, 220 ohms + (.115uf || 820 ohms) A-law Austria, Germany, Mexico, Switzerland. Index 8, 270 ohms + (.120uf || 910 ohms) A-law Finland There are 19 listings, but only 3 of which are ulaw (Japan, Korea, US/Taiwan). > Does the server need to reencode it at all, or is the codec the same > on Euro ISDN? > If it has to reencode everything, it really seems to be CPU critical > when using 30 FSX lines into 30 Euro ISDN lines. >From ulaw to Alaw shouldn't be compute intensive, it shouldn't be more than a bit munge.

FXS is for pointing at a station(phone) FXO is for pointing at a office(telco) For phones attached directly, you need FXS ports. > ----- Original Message ----- > From: "Steven Critchfield" <[EMAIL PROTECTED]> > To: "Asterisk Users Mailing List - Non-Commercial Discussion" > <[email protected]> > Sent: Monday, January 17, 2005 2:57 PM > Subject: Re: [Asterisk-Users] CAS voice signalling? > > > > On Mon, 2005-01-17 at 14:33 +0100, Daniel Nystr�m wrote: > > > According to CarrierAccess, the Adit 600 uses CAS for voice signalling. > > > What is this? > > > This should not be a problem for Asterisk? > > > Does the Asterisk server need to reencode CAS into aLaw when going to > > > Euro ISDN? > > > > CAS is Channel Associated Signaling.
