[SR-Users] Comunication between devices RTP/SRTP and viceversa

[Social Boh]

I'm trying to configure Kamailio to permit communication between devices:

some use TLS and SRTP

some UDP and RTP

with RTPEngine in the middle.

A priori I don't know if the device support SRTP or RTP so in the 
routing I have to detect on the fly how to act. The problem is this:

Call from RTP to SRTP device: 488 Not Acceptable here

Call from SRTP to RTP device: 415 Unsupported Media Type

Any hint?

Thank you

  Regards
