Dear list, We have an weird problem with our FXO card (TDM01B). When I made a call using this channel, all goes well, the called phone rings but when the called phone answers the call. In me handset I can hear an weird sound like a "Clack". I tryed diferents TDM cards and modules, and my zapata.conf is like,
language=en context=from-zaptel switchtype=national usecallerid=yes callerid=asreceived transfer=yes callreturn=yes rxgain=-3.0 txgain=-3.0 immediate=no busydetect=yes busycount=8 answeronpolarityswitch=yes hanguponpolarityswitch=yes ringtimeout=8000 faxdetect=both group=0 signalling=fxs_ks channel => 7 think the problem is not by echo cause I use fxotune, and the problem persist. I made lots of TDM02B instalations and never get this kind of problem. Any clue will be welcomed. Thanks in advance. Regards VoipCrazy
