[asterisk-ss7] MATTF libss7

[Konstantin Prokazoff]

Hi Atilla again...

Are your think so? Yes, it is coded to send it, but movement between
different states of MTP2 goes too fast on modern CPU, so, some states
can't be reached at ALL.
For example, there are T17 timer at MTP3 layer, which isn't implemented.
But it is still required for libss7 to work as described in ITU.

BR,
K.
