Error description

• Modification to From header in initial request is lost when
  creating a branch request. The From header should be the same
  as in the (modified) incoming request.
  
  
  Example:
  
  enable.system.headers.modify container custom property is set to
  'true'
  
  Incoming INVITE, note Request-URI = sip:1234444@avaya.com, From:
  "Simple \"CTR\"" <sip:  6610008@1.2.3.45>;tag=1
  
  Application modifies request-URI to sip:1114444@avaya.
  com, and From header to Fom: "Simple \"CTR\""
  <sip:7710008@foo.com>; tag=1
  
  Incoming request logged immediately before calling Proxy.
  createProxyBranches Line 1750:  Code calls log.finest("Created
  proxy branches;
  
  branch Req is " + proxyBranchList.get(0).getRequest()); Branch
  request is printed.  The From header in the branch request does
  not reflect the modification that was made to the incoming
  request:  From:  "Simple \"CTR\"" <sip:6610008@1.2.3.45>;tag=1

  From and To headers are saved in cache for proxy requests and
  responses. The cache is not cleared when the value of those
  headers is changed
  

Problem conclusion

• When To or From headers value is changed their cached value is
  now cleared, and the new value is saved
  
  The fix for this APAR is currently targeted for inclusion in
