Dear list,<br><br>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,<br>
<br>language=en<br>context=from-zaptel<br>switchtype=national<br>usecallerid=yes<br>callerid=asreceived<br>transfer=yes<br>callreturn=yes<br>rxgain=-3.0<br>txgain=-3.0<br>immediate=no<br>busydetect=yes<br>busycount=8<br>answeronpolarityswitch=yes<br>
hanguponpolarityswitch=yes<br>ringtimeout=8000<br>faxdetect=both<br>group=0<br>signalling=fxs_ks<br>channel => 7<br><br>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.<br>
<br>Any clue will be welcomed.<br><br>Thanks in advance.<br><br>Regards<br><br>VoipCrazy<br> <br><br>
