  Be consistent, send From: "Anonymous" <sip:anonymous@anonymous.invalid>
  
  When setting CALLERID(pres)=unavailable in the dialplan, the From header
  in the SIP message contains "Anonymous" <sip:Anonymous@anonymous.invalid>.
  For consistency, Asterisk should use a lowercase a in the userpart of the
  URI.
  
  * Make the From header use a lowercase A in the userpart of the anonymous
  URI.

  Revert change to res_rtp_asterisk committed in r373236 (1.8)
  
  The change committed in r373236 attempted to account for endpoints that
  increased their RTP timestamp in DTMF end of event re-transmissions.  This
  change attempted to make Asterisk continue to work with endpoints that
  failed to follow the RFC while maintaining the fix that allowed for out of
  order DTMF to be handled.  Unfortunately, there is no free lunch, and this
  patch broke any system that sent DTMF immediately after an RTP session was
  established or when an SSRC is updated.  As such, that patch is being
  reverted for the previous behavior.
  
  Endpoints that erroneously increase the RTP timestamp in DTMF end of event
  packets will not work properly with Asterisk.
