[Freeswitch-users] Get ZRTP SAS from other side of MITM call

Folks;

 

Scenario:

 

Non ZRTP UA (local extension) ßà FS MITM ßà ZRTP UA via gateway

 

I am attempting to get the ZRTP SAS from the ZRTP call which is received via
gateway and bridged to Non ZRTP UA

 

It appears that in MITM scenario, the aleg uuid (for non-ZRTP call) is
identical (recycled less security variables) to the ZRTP aleg uuid

 

Is there any way to get variables (luarun script) from the ZRTP call (other
side of MITM) from within the uuid context of the non ZRTP call?

 

Or, other suggestions, since my newbie status is inevitably “missing
something”

 

Thanks;

Bill Ross
