Hi thx.
I tried without double back slashes. Has no effect.
But I already resolved it with different way
Just decoded message to base64 formt  and then sent to needed service where i encoded it and parsed (thx Alex Balashov for 2014 kamailio world presentantion)
Was not sure about parsing string by kamailio (this it is not a best idea), think that logic on kamailio side should be as clear as it posible

can you try with:

$var(body)=$(rb{s.rm,\n});

or:

$var(body)=$(rb{s.rm,\\n});

Not sure if needs double back slashes, that's why I said to try the both.

Cheers,
Daniel
