The ztmonitor app is a relative indicator and is not actually calibrated to anything. If your play in the telephony marketspace, then purchase a transmission test set that can display levels, etc. They are made by several different companies and range in price from about $300 for a simple analog test set (looks almost like a voltmeter), to well over $3k for fancy ones that have dsl test modes, etc. Triplett (www.triplett.com) makes several different models of which the model 4 & 5 have a tone generator that can be somewhat useful as well. Lots of other sources for the same. _______________________________________________ Asterisk-Users mailing list [EMAIL PROTECTED] http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
