Lonnie, I didn't have double quotes around the parameter, which I have since added, but it didn't help (still have the echo). After examining the console output from my Soekris box during bootup, it looks like oslec is loading:
---------------------------------------------------------- dahdi_echocan_oslec: Registered echo canceler 'OSLEC' dahdi: Registered tone zone 0 (United States / North America) wanpipe1: Open (usecount=1, channo=1, chanpos=1)... wanpipe1: Open (usecount=1, channo=2, chanpos=2)... wanpipe1: Open (usecount=1, channo=3, chanpos=3)... wanpipe1: Open (usecount=1, channo=4, chanpos=4)... ---------------------------------------------------------- I also see that the Sangoma board has a h/w ec module, which is erroring out: ---------------------------------------------------------- --> Loading ec image OCT6116-64S.ima... wanpipe1: Clear Echo Canceller chip reset. wanpipe1: Module 1: FXO Line is disconnected! wanec1: Opening HW Echo: [Mode=Normal NoiseRed=Off VQE=1836 DtmfRmv=Off Acust=Off NLP=On ] wanec1: Opening HW Echo: [Mode=Normal NoiseRed=Off VQE=1836 DtmfRmv=Off Acust=Off NLP=On ] wanec1: Opening HW Echo: [Mode=Normal NoiseRed=Off VQE=1836 DtmfRmv=Off Acust=Off NLP=On ] wanec1: Opening HW Echo: [Mode=Normal NoiseRed=Off VQE=1836 DtmfRmv=Off Acust=Off NLP=On ] sh: wan_ec_clienwanpipe1: Set Echo Canceller chip reset. t: command not found --> Error: system command: wan_ec_client wanpipe1 be all wanconfig: Failed to Bypass enable EC device wanpipe1 (err=127)! wanconfig: HWEC configuration failed on wag1 Please check /var/log/wanrouter and /var/log/messages for errors. Configuring interfaces: wag1 done. ---------------------------------------------------------- I will contact Sangoma to diagnose error 127, but would the hardware EC affect the operation of oslec? I also found some other problems with the firewall while investigating this issue. I will post that info to a separate thread. Thanks again for all your help. -tm -----Original Message----- From: Lonnie Abelbeck [mailto:li...@lonnie.abelbeck.com] Sent: Monday, March 14, 2011 5:28 PM To: AstLinux Users Mailing List Subject: Re: [Astlinux-users] OSLEC configuration Tom, Maybe you have a typo, the user.conf via the web interface should contain: -- DAHDIMODS="dahdi_echocan_oslec" -- Lonnie On Mar 14, 2011, at 3:45 PM, Tom Mazzotta wrote: > Giovanni, > > I updated the system.conf and chan_dahdi.conf as you suggested.
