Hi, I recently installed a TE120P in my lab with a full voice PRI (23 channels + 1 D channel). Everything is working well except echo cancellation; for the most part this isn't an issue unless one of the users is in a conference.
I'm getting the following error when a call is picked up (incoming or outgoing): [Feb 25 12:54:01] WARNING[8661]: chan_zap.c:1437 zt_enable_ec: Unable to enable echo cancellation on channel 1 (Argument list too long) Here's my zapata.conf: [channels] group=1 signalling=pri_cpe switchtype=national context=external channel=1-23 echocancel=yes echocancelwhenbridged=yes The error occurs with or without the two echo statements. I haven't been able to find anything on this error. Can someone point me in the right direction to troubleshoot this? Thanks in advance!
