Hi, A number of odd behaviors were reported today including remote worker not working and basic calls generating an abnormally large number of ACKs leading to endpoints timing out.
I looked into these problems and found that they had a common root cause which is that the sipXproxy does not see the INVITEs resulting from the 302 redirection. This behavior is caused by the fact that sipXregistrar does not call the AuthRouter redirect plug-in which normally ensures that sipXproxy sees these redirected INVITEs. Further investigation revealed that this plug-in wasn't called because it was preceded in the registrar-config file by the HuntGroup redirect plug-in who is no longer with us :) That caused the Redirect Server to skip all redirect plug-ins that followed it. The short-term fix which I will commit shortly is to remove the HuntGroup redirect plug-in from the registrar configuration file but once this is done, I'll try to figure if there is an easy way to harden the SIP Redirect server to cope with plug-ins whose library won't load... Cheers, bob
