  Unable to originate calls using E&M over T1.
  
  When originating a call from Unit Under Test to Reference Unit using E&M
  RBS signaling mode, I get the following warning message: "Ring/Off-hook in
  strange state 3 on channel 1".
  
  Fixed the sig_analog outgoing flag.  It was never set when sig_analog was
  extracted from chan_dahdi.
  
  JIRA SWP-2191
  JIRA AST-408
