  SIP register not using peer's outbound proxy
  
  If callbackextension is defined for a peer it successfully causes
  a registration to occur, but the registration ignores the
  outboundproxy settings for the peer.  This patch allows the
  peer to be passed to obproxy_get() in transmit_register().
  
  (closes issue #14344)
