Hi Guys, My server was working fine till today, It does not transfer any call. When I call an extension i get  a not connected tone and in the log I see invalid application 2012-06-22 09:37:26.414815 [ERR] switch_core_session.c:2156 Invalid Application transfer I wonder what this could be? I was trying yesterday to install some packages. Could this be related to that? kind regards, Sherif
