Hello, I've connected a Sangoma E1 card without Echo Cancel. I'm using FreeTDM (Wanpipe Mode). My card does't have echo cancel by hardware. Is there some way to configure soft echo cancel in my current configuration (Wanpipe Mode)? Something like Oslec or MG2. Thanks, This is my current config: *conf/freetdm.conf* [span wanpipe wp1] trunk_type => e1 b-channel => 1:1-15 d-channel => 1:16 *autoload_configs/freetdm.conf.xml* <configuration name="freetdm.conf" description="Freetdm Configuration"> <settings> <param name="debug" value="0"/> <!--<param name="hold-music" value="$${moh_uri}"/>--> <!--<param name="enable-analog-option" value="call-swap"/>--> <!--<param name="enable-analog-option" value="3-way"/>--> </settings> <config_profiles> <profile name="telco_1"> <param name="switchtype" value="euroisdn" /> <param name="signalling" value="cpe" /> <param name="overlap" value="yes" /> <param name="facility" value="yes" /> </profile> </config_profiles> <sangoma_pri_spans> <span name="wp1" cfgprofile="telco_1"> <param name="dialplan" value="XML"/> <param name="context" value="from-pstn"/> </span> </sangoma_pri_spans> </configuration> -- -- Raúl Baldeón Area de Soporte - Infobox Latinoamérica Tel. +511 7129130 Anexo 41 -- -- Raúl Baldeón Area de Soporte - Infobox Latinoamérica Tel. +511 7129130 Anexo 41
