[SR-Users] Which mode to capture "written to network" traffic with homer and topos

[Karsten Horsmann]

Hi Daniel,

in that case it works (also with topos and then sipcapture). With your
suggestion.

In my other case (as webrtc and tls registrar) I needed the function to see
Kamailio self created traffic and so, imho.

Thanks for the hints.

Cheers
Karsten
