I recently upgraded my Asterisk system to Dahdi and now I have an echo
problem. I am running Asterisk 1.4.25 with Dahdi Complete 2.2.0, on a Digium TE121B PCI express card with a HARDWARE echo cancellation module. All this is housed on a CentOS 5.5 box, 2.6.18 Kernel. My incoming phone service is an AT&T PRI (24 channel T1). My configs: ********chan_dahdi.conf********* [channels] ; configuration for T1 card as PRI language = en group = 1 echocancel = yes echotraining = yes signalling = pri_cpe switchtype = 4ess usecallerid = yes context = incoming channel => 1-23 ***********/etc/dahdi/system.conf************* loadzone=us defaultzone=us span=1,0,0,esf,b8zs bchan=1-23 dchan=24 When I run dahdi_cfg -vvv I get the following: DAHDI Tools Version - 2.2.0 DAHDI Version: 2.2.0.1 Echo Canceller(s): MG2 Configuration ====================== SPAN 1: ESF/B8ZS Build-out: 0 db (CSU)/0-133 feet (DSX-1) Channel map: Channel 01: Clear channel (Default) (Echo Canceler: none) (Slaves: 01) Channel 02: Clear channel (Default) (Echo Canceler: none) (Slaves: 02) Channel 03: Clear channel (Default) (Echo Canceler: none) (Slaves: 03) Channel 04: Clear channel (Default) (Echo Canceler: none) (Slaves: 04) Channel 05: Clear channel (Default) (Echo Canceler: none) (Slaves: 05) Channel 06: Clear channel (Default) (Echo Canceler: none) (Slaves: 06) Channel 07: Clear channel (Default) (Echo Canceler: none) (Slaves: 07) Channel 08: Clear channel (Default) (Echo Canceler: none) (Slaves: 08) Channel 09: Clear channel (Default) (Echo Canceler: none) (Slaves: 09) Channel 10: Clear channel (Default) (Echo Canceler: none) (Slaves: 10) Channel 11: Clear channel (Default) (Echo Canceler: none) (Slaves: 11) Channel 12: Clear channel (Default) (Echo Canceler: none) (Slaves: 12) Channel 13: Clear channel (Default) (Echo Canceler: none) (Slaves: 13) Channel 14: Clear channel (Default) (Echo Canceler: none) (Slaves: 14) Channel 15: Clear channel (Default) (Echo Canceler: none) (Slaves: 15) Channel 16: Clear channel (Default) (Echo Canceler: none) (Slaves: 16) Channel 17: Clear channel (Default) (Echo Canceler: none) (Slaves: 17) Channel 18: Clear channel (Default) (Echo Canceler: none) (Slaves: 18) Channel 19: Clear channel (Default) (Echo Canceler: none) (Slaves: 19) Channel 20: Clear channel (Default) (Echo Canceler: none) (Slaves: 20) Channel 21: Clear channel (Default) (Echo Canceler: none) (Slaves: 21) Channel 22: Clear channel (Default) (Echo Canceler: none) (Slaves: 22) Channel 23: Clear channel (Default) (Echo Canceler: none) (Slaves: 23) Channel 24: D-channel (Default) (Echo Canceler: none) (Slaves: 24) 24 channels to configure.

Is that the harwdare module? Do I even need to specify an echo canceller in the configs if I have a hardware echo module? --
