ADD Operation

# Sample SMM Rules to manipulate SDP content using the ADD operation
#
# Rule 1 Action 1: add line "i=i-line" to session block
# Rule 1 Action 2: add line "i=i-line" to first instance of audio stream
# Rule 1 Action 3: add line "a=rtpmap:8 PCMA/8000 " to first instance of audio stream
