[asterisk-ss7] Internal protocol analyzer

Do you know if libss7 has the same capabilities?  But let's say we use these SS7/ISDN capable cards as a SS7 or ISDN protocol analyzer, no such development work there?  Digium, Sangoma?

Why ask for two or more, when you can try and get it all in one.

But this is also good to know about Wireshark.

In chan_ss7, you can use the command "ss7 dump start ..." to send protocol
data to a file, and then use ethereal (now renamed to wireshark) to analyze

For details, see
