Hi, I have a FXO line in TDM410P card. Over some calls, after a few minutes of conversation, a busy tone occurs on the call. The call remains up, the two sides of the call is heard normally, but remains a busy tone in the middle of the conversation. When this occurs in the log appears the following: Jul 10 13:22:45 DEBUG[11688] chan_zap.c: Got event Polarity Reversal(17) on channel 2 (index 0) Jul 10 13:22:45 DEBUG[11688] chan_zap.c: Ignore switch to REVERSED Polarity on channel 2, state 6 Jul 10 13:22:45 DEBUG[11688] chan_zap.c: Ignoring Polarity switch to IDLE on channel 2, state 6 Jul 10 13:22:45 DEBUG[11688] chan_zap.c: Polarity Reversal event occured - DEBUG 2: channel 2, state 6, pol= 0, aonp= 0, honp= 0, pdelay= 600, tv= 1706049808 Anybody know how to fix this problem? I tried to add relaxdtmf=yes in zapata.conf but the problem persisted. zapata.conf [channels] context=default rxwink=300 usecallerid=yes hidecallerid=no callwaiting=no usecallingpres=yes restrictcid=no callwaitingcallerid=yes threewaycalling=yes transfer=no cancallforward=no callreturn=yes echocancelwhenbridged=yes echotraining=yes rxgain=0.0 txgain=-2.0 group=1 callgroup=1 pickupgroup=1 faxdetect=no immediate=no musiconhold=default echocancel=yes relaxdtmf=yes context=default busydetect=no context=default signalling=fxs_ks group=2 channel=>1-3 Thank you. -- Marcus ____________________________________________________________________________________ Veja quais s?o os assuntos do momento no Yahoo! +Buscados http://br.maisbuscados.yahoo.com -------------- next part -------------- An HTML attachment was scrubbed...
