[SR-Users] rtpengine via-branch=extra question

rtpengine readme tells:

  via-branch=... - Include the “branch” value of one of the “Via” headers
  in the request to the RTP proxy. Possible values are: “1” - use the
  first “Via” header; “2” - use the second “Via” header; “auto” - use the
  first “Via” header if this is a request, or the second one if this is a
  reply; “extra” - don't take the value from a header, but instead use the
  value of the “extra_id_pv” variable. This can be used to create one
  media session per branch on the RTP proxy. When sending a subsequent
  “delete” command to the RTP proxy, you can then stop just the session
  for a specific branch when passing the flag '1' or '2' in the
  “rtpengine_delete”, or stop all sessions for a call when not passing one
  of those two flags there.

if via-branch=extra is used in offers of branched, should it also be
used in answers and deletes?
