It looks like that chan_ss7 is checking whether the incoming number
matches any extension, just before it gets the whole number?
Therefore chan_ss7 doesn?t expect other SAM's, because there is not a
matching extension
After that it never goes to second choise, where it starts the timer,
RIGHT?
My ;
enable_st is yes
static void check_iam_sam(struct ss7_chan* pvt)
{
int complete = (pvt->link->linkset->enable_st &&
pvt->iam.dni.complete) ||
ast_exists_extension(pvt->owner, pvt->context, pvt->iam.dni.num, 1,
pvt->iam.rni.num);
if (complete) {
pvt->iam.dni.complete = 1;
ast_log(LOG_DEBUG, "Setting iam.dni.complete\n");
handle_complete_address(pvt);
} else {
if (ast_canmatch_extension(pvt->owner, pvt->context,
pvt->iam.dni.num, 1, pvt->iam.rni.num) != 0) {
ast_log(LOG_DEBUG, "Processing addr %s, incomplete, starting
T35\n", pvt->iam.dni.num);
t35_start(pvt);
}
else {
ast_log(LOG_DEBUG, "Unable to match extension, context: %s, dni:
%s, rni: %s\n", pvt->context, pvt->iam.dni.num, pvt->iam.rni.num);
initiate_release_circuit(pvt, AST_CAUSE_UNALLOCATED);
}
}
}

Hi
I think chan_ss7 is not waiting enough for SAM's
Maybe there is an wrong conditional statement in source, that complets
digit receipt or maybe t35?
And what we are experiencing here is also, if the other switch start
sending slowly overlap then chan_ss7 sends a CON and basically this is
the finish of dialing.

There definitively is a bug in 0.8.4 in the handling of SAM overlapped
dialing. I don't know if it is fixed in 0.9 as I don't use it, but in
0.8.4
I needed to patch it. I will look what the problem was exactely and post
the patch if wanted.
Best regards,
Kai
