Summary: Change to allow SIPP to support binary ISUP message body
Initial Comment:
Code modifications to allow binary input including \x00 to be specified in a
scenario. This was needed to support SIP-I and SIP-T to allow an encapsulated
binary ISUP message in the message body.
The current implementation of SIPP was treating the data it processed from the
scenario file as a string, so any attempt to input a binary 0 as \x00 was being
interpreted as a null terminator and truncating the message at this point.
I haven’t had to make any changes on the receive message processing to get this
working. I guess things are just working ok because any received ISUP data is
in the body at the end of the message so doesn't impact on any string
processing on the headers.
I’ve done limited testing on this feature, just running the following scripts
back to back, but these seem to be working ok:
