If anyone is interested, I've added a line to the "upgrade.sh" file, to automatically remove the RADIO_RELAX parameter when upgrading your Asterisk to the latest SVN release. My system experiences quite a bit of DTMF false decodes with the RADIO_RELAX parameter in place, and it's easy to forget that step when recompiling. wget http://www.qsl.net/k0kn/upgrade.sh 73 Kyle Yoksh K0KN Olathe, KS
