[RTPproxy Users] correct meaning of force_rtp_proxy "E" and "I" flags in bridge mode

[Klaus Darilion]

Hi!

When rtpproxy is in bridging mode, and the session is created (INVITE) 
with "I" flag (internal), what command should be specified during lookup 
  (200 ok response) to select the other interface?

Do I have to use the 'E' flag to select the other interface, or do I 
have to specify again the 'I' flag and rtpproxy automatically choose the 
other interface (as it is a lookup)?

regards
