Hi, In my case the echo canceller works, but sometimes too effectively - it cuts out the remote party sometimes. I've been playing with the gains, but if my txgain is less than 3 or so, the remote party reports us as being very soft, or can't hear us at all.

My leds are being lit up in order, it's a nice fade effect. > Messages from /var/log/messages: > May 29 09:41:38 pbxtest kernel: VPM: Chip 0: ver 33 > May 29 09:41:38 pbxtest kernel: VPM: U-law mode > May 29 09:41:38 pbxtest kernel: VPM: Chip 1: ver 33 > May 29 09:41:38 pbxtest kernel: VPM: Chip 2: ver 33 > May 29 09:41:38 pbxtest kernel: VPM: Chip 3: ver 33 > May 29 09:41:38 pbxtest kernel: VPM: DTMF threshold set to 1250 > May 29 09:41:38 pbxtest kernel: VPM: Present and operational [4720736.996000] Port 24: Installed -- AUTO FXO (AUSTRALIA mode) [4720737.006000] VPM Revision: 09 [4720737.026000] VPM: U-law mode [4720737.282000] VPM: DTMF threshold set to 1250 [4720737.282000] VPM: Present and operational (Rev A) [4720737.282000] Found a Wildcard TDM: Wildcard TDM2400P Prototype (24 modules) [4720779.486000] Registered tone zone 1 (Australia) is what I get - it doesn't go through the chips individually, zaptel 1.2.4 > Another question for you: > which kind of test or instrument do you use to analyze echo on analog > lines?
