The instructions to build rtpengine work, have you tried those?

Take a look at the readme file. Last I used was v6 and that worked properly for me.

so can you give me a configuration template ?

so if i understand correctly, for the srtp > rtp conversion, i should use a box (asterisk for example) 
in the middle,

is there any alternative to rtpengine ?

Thanks You

Hi,

its simple: They need srtp so you make your pbx to accept srtp,
or have a box(pbx) before it to accept srtp and terminate to your pbx that does not suport srtp?...

I had it working to kamailio and softphones.

Hello everybody!

i am trying a setup of kamailio like sbc for ms teams,
I currently have the following scenario:

TLS Connection OK

Out Call ok (except BYE 481 on reply)

my problem is in incoming calls
microsoft only supports srtp
and my pbx (freeswitch based) only works with rtp,

now i was reading that you need to use rtpengine to manage srtp to rtp,

unfortunately it seems that rtpengine has become very difficult to build especially with recent os,
I was wondering if it is possible to have an alternative to rtpengine for managing the srtp (rtpproxy does not seem to work)

has anyone managed to get a working setup?

in case it is possible to send a configuration template?

Thanks You !!!

Davide
