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:<br><br>Jul 10 13:22:45 DEBUG[11688] chan_zap.c: Got event Polarity Reversal(17) on channel 2 (index 0)<br>Jul 10 13:22:45 DEBUG[11688] chan_zap.c: Ignore switch to REVERSED Polarity on channel 2, state 6<br>Jul 10 13:22:45 DEBUG[11688] chan_zap.c: Ignoring Polarity switch to IDLE on channel 2, state 6<br>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<br><br>
<br>Anybody know how to fix this problem?<br><br>I tried to add relaxdtmf=yes in zapata.conf but the problem persisted. <br><br>zapata.conf<br><br>[channels]<br>context=default<br>rxwink=300<br>usecallerid=yes<br>hidecallerid=no<br>callwaiting=no<br>usecallingpres=yes<br>restrictcid=no<br>callwaitingcallerid=yes<br>threewaycalling=yes<br>transfer=no<br>cancallforward=no<br>callreturn=yes<br>echocancelwhenbridged=yes<br>echotraining=yes<br>rxgain=0.0<br>txgain=-2.0<br>group=1<br>callgroup=1<br>pickupgroup=1<br>faxdetect=no<br>immediate=no<br>musiconhold=default<br>echocancel=yes<br>relaxdtmf=yes<br>context=default<br>busydetect=no<br><br>context=default<br>signalling=fxs_ks<br>group=2<br>channel=>1-3<br><br><br><br> <br>Thank you.<br><br><br>--<br>Marcus<br><br></div></div><br>
