It's not the normal working state of chan_sip, in fact it hasn't really 
been touched in any way that would cause this to happen and I haven't 
seen any bug reports along these lines. I also know that FreePBX is 
running both chan_sip and chan_pjsip and haven't experienced anything so 
it may be isolated to you. If you follow the instructions on the wiki[1] 
it will provide a backtrace which will show where chan_sip is hanging.
