I'm not sure what type of "phone" you are on, but some of the SIP users at my job get the echo when their MIC is turned up too much. The SIP phone, from one * to another *, is hooked into ZAP channels.
SIP Client ----> SIP Server ----> ZAP Server ----> T1 connection If the SIP Client goes too high with the MIC, no good. Not sure if that helps. Or provides any insight. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Gregory Wiktor - ADCom Corp.

Static is gone, although quality so far seems not quite there yet. I am also experiencing an odd local echo. I can hear a slight echo locally, but the other end sounds fine, and the other end does not get echo. Even with the pots disconnected, you can hear it. The static would be on all calls. Hooking up a normal phone was ok. The sip>sip phones are perfect too, it was only happening on the zap channel...

Have you tried a different phone? Does the static appear immediately when you pick up the phone? Or on the second or third time? _______________________________________________ Asterisk-Users mailing list Asterisk-Users@lists.digium.com http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users _______________________________________________ Asterisk-Users mailing list Asterisk-Users@lists.digium.com http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users -- No virus found in this outgoing message.
