             Project: Asterisk
          Issue Type: Bug
      Security Level: None
          Components: Channels/chan_sip/General
    Affects Versions: 1.8.20.1
         Environment: Gentoo Linux 3.2.12-gentoo #2 SMP Mon Jun 4 14:49:23 MSK 2012 x86_64 Intel(R) Xeon(R) CPU X5660 @ 2.80GHz GenuineIntel GNU/Linux, based on VMWare virtual system, Phones: Cisco SPA502, Cisco SPA525 with SPA 500S panels. Using SIP realtime. 
            Reporter: c0rnoTa


After a while of working, system stop to process calls from sip subscribers. If I call to someone from console, I didn't set that system is 'Calling SIP/...' and INVITE pockets are not sent.
Asterisk was compiled without optimization.

But here is only 'show locks' output:
