Hello,

I am using freeswitch version 1.3.13b as a voip server and csipsimple as a sip client. Also using TLS and SRTP for security issues. 

When making call I got "503 / End of file (PJ_EEOF)" error many times. I thought that I have problem with some timeouts. Because when I try to call someone, the first try %80 fails, second one (but immediate ones after the first one) %80 successes. But if I wait for 15-30 seconds at least, I got this error again. 

I also out the logs : http://pastebin.freeswitch.org/21246

Thank you, regards...
