[OpenSIPS-Users] How to store SRTP keys of 200 OK?

Hello all,

For video recording and playback, I need to store the SRTP keys in SDP of
INVITE and 200 OK (the call is protected over SRTP). For INVITE, I can use
``exec_avp("echo 1 $rb | nc 10.100.13.11 7003", "$avp(vch)");'' to pass the
SDP to some external process. However, exec_avp cannot be invoked on
reply_route. Does anyone have some suggestion on this issue? Any help is
greatly appreciated.

Best wishes,
Chen-Che
