Saw an issue with someone back in 2010 had this issue but did not see a resolution. Here's what I have a Coral 3000 with a QSIG connection to an Aeonix server. (Slowly cutting over) Aeonix has been up and working for a while then all of a sudden not able to pass a call across it. Have rebooted the Aeonix and reset the PUGW card in th Coral yet the same error above. When I turn n on messaging on the Coral all I see is a 2h code. Turn on TCPDUMP on the Aeonix ( tcpdump -I eth0 | grep nothing comes across. (Opened another ssh session and ran ping to th PUGW and then saw traffic on tcpdump so connectivity is good) only about 45 phones on the Aeonix minimal traffic between these 2 switches. Ran into this onc before a very long time ago but for the life of me cannot remember what the solution was. Anyone got any ideas?
