I'm taking use of below call model:SIP<--->mod_sofia ---- mod_freetdm---[sangoma]--wanpipe<-->E1Now, I want to get the raw ISUP at [sangoma] part. The current situation is, the wanpipe provides some ISUP message structures in "sit.x", which is the extractor of raw ISUP.Anyone know how to get the raw ISUP excepte to re-encode from the structure? Is there any API?
Only way to get raw MSUs is to use the C API libsangoma.
See this for an example: https://github.com/moises-silva/sng_ss7mon
