[OpenSIPS-Users] Access specific SDP line

[microx]

Hi all, 

For some reason, I would like to fetch the SDP attribute crypto to get the
encryption key for SRTP.
To achieve this, as far as I know, SDP Transformations (e.g, $var(aline) =
$(rb{sdp.line,a,1})) seem 
the only way that I can use to retrieve the desired encryption key. However,
this approach is  inefficient 
because I have no idea on which line the encryption key is. Does anyone have
any better suggestion on this issue?
Many thanks for any help or comment.

Best regards,
Chen-Che
