I dont know if your case is one of those. If you wish to try, I suggest<br>re-compiling Asterisk with the RADIO_RELAX compile parameter turned off, and see if you like it<br>that way better. I can guarantee you that you will have less "falsing" if you do that. What I can not<br>guarantee is that you will get all the "real" digits decoded reliably (if you do that).<br><br>Jim WB6NIL<br><br><div><div id="SkyDrivePlaceholder"></div><hr id="stopSpelling">From: <a href="mailto:adamson_alan@hotmail.com">adamson_alan@hotmail.com</a><br>To: <a href="mailto:app_rpt-users@ohnosec.org">app_rpt-users@ohnosec.org</a><br>Date: Sun, 3 Jun 2012 15:26:06 -0400<br>Subject: [App_rpt-users] RTCM falsing DTMF<br><br><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; padding-top: 0px; padding-right: 0px; padding-bottom: 0px; padding-left: 0px; "><span lang="en-us"><font face="Calibri">ok, so is it normal for the RTCM to get false DTMF when voice is doing over the link?
