It looks like Asterisk pays no attention to the "slc" setting in
chan_dahdi.conf, but instead libss7 (in ss7.c) automagically calculates the
Signaling Link Code based on how many are linksets have been defined:
/* ****************** */
// looks like we create a new mtp2 link and autoincrement the SLC counter
m = mtp2_new(fd, ss7->switchtype);
if (!m)
return -1;
m->slc = ss7->numlinks;
ss7->numlinks += 1;
m->master = ss7;
if (zapmtp2)
m->flags |= MTP2_FLAG_ZAPMTP2;
ss7->links[ss7->numlinks - 1] = m;
/* ****************** */
So changed it to add one (m->slc = ss7->numlinks + 1) and I'm getting MTP2 link
issues:
