Without more technical data, its hard to guess. Might consider... 1. if you're using cisco phones, upgrade * to current Head or Stable on "both" ends of the iax link. The Stable code was just fixed on Friday. (There could be other phones/adapters that are impacted by the iax/gsm timestamp problems.) I've also noticed a fair number of other fixes that were just recently applied to Head. 2. if not cisco phones, check the config's on whatever phone you're using to ensure "transmit silence" is enabled. If you are using the xten soft phone, the parameter is in the Advanced Settings area. 3. Check to ensure all ethernet nic adapters (and associated switch ports) are running in full-duplex mode, etc. 4. If none of the above apply, it would be helpful to see a packet trace (using ethereal) at about the time the distorting/failure is occurring. _______________________________________________ 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
