Dull as it may seem read BT's SIN351 twice to make sure I was correct on the tones and z, tried both aLaw and uLaw. Strangely the PSTN-SPA gain made marginal difference, especially when echo supp/cancel were enabled. The weird thing is I decided to turn all echo cancel off and played with the z settings and seemed to get the same amount of reflected echo.
Maybe Cisco can do a better job? ;o) -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Chris Stenton Sent: 26 April 2005 17:13 To: Asterisk Users Mailing List - Non-Commercial Discussion Subject: Re: [Asterisk-Users] Good FXO for UK use. I find the voice quality fine on the 3000. Have you set the line Z etc correctly and used ulaw?
