Update The funny warning message comes from the fact that iaxRpt is not compatible with port address translation (PAT). I switched to the "bindport" method of changing the port number. But I still have the original problem: one node connects, the other does not. The connection that works looks like this: -- Executing [27061@radio-gui:1] Rpt("IAX2/gui-5701", "27061|X") in new stack The one that does not work looks like this: -- Executing [27021@radio-gui:1] Rpt("IAX2/gui-5264", "(27021|X)") in new stack == Parsing '/etc/asterisk/rpt.conf': Found == Parsing '/var/lib/asterisk/rpt_extnodes': Found [Jan 2 20:11:37] WARNING[24086]: app_rpt.c:20884 rpt_exec: Cannot find specified system node (27021 The obvious difference being the left parenthesis ahead of the node number. It seems that Asterisk is being asked to connect 27061 in one case and "(27021" in the other case. And Asterisk is complaining about a node whose number starts with a "(" I cannot figure out where the extra "(" is coming from.. Tnx Ken
