  ACL check not present for verifying SIP INVITEs 
  
  The ACL check in check_peer_ok was missing and has now been restored. The
  missing check allowed for calls to be made on prohibited networks where an ACL
  was defined in sip.conf and the allowguest option was set to off. See the AST
  security advisory below for more information.
  
  Merge code associated with AST-2009-007.
  
  (closes issue #16091)
