Hi!

I’m trying to get SDP body in my var.

I’m using smth like this

    if (KSR.textops.has_body() ~= -1 and
KSR.textops.has_body_type("application/sdp")
~= -1) then
        KSR.textops.get_body_part("application/sdp", "$var(pbody)»)
local sdp_body = KSR.pv.get("$var(pbody)")
….
    end

But in logs i see this
LUA {INVITE}:  7(20794) DEBUG: <core> [core/parser/msg_parser.c:183]:

ki_get_body_part_helper(): Cannot get boundary. Is body multipart?

Was there a multi-part body? If not, get the body with $rb variable.

Cheers,
Daniel


So, in sdp_body var i got 0. What is wrong here?
