Can somebody maybe explain me what this code means
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);
I think that the problem is here or in my understanding about this piece
of code. We have to understand, what the conditions are to first or to
second choise of this if else statement
thank you very much

I think chan_ss7 supports overlapped signalling on incoming calls:
static void process_sam(struct ss7_chan *pvt, struct isup_msg
*inmsg)
{
...
strcat(pvt->iam.dni.num, inmsg->sam.sni.num);
pvt->iam.dni.complete = pvt->iam.dni.complete ||
inmsg->sam.sni.complete;
check_iam_sam(pvt);
}
So on reception of SAM (subsequent address message), it just collects
the
digits.
Overlapped signalling is not supported for outgoing calls. This is
mostly
because there is no API in Asterisk for this (or at least there was not
when I
implemented the original version of chan_ss7).
I guess in the VoIP, overlapped dialing is not usual, as there usually
is a
full address before a call is initiated, and Asterisk works the same
way.
- Kristian.
