I've bin trying and searching through the source code, and I currently
have this:
So the connection should be:
1 x E1 link a to PC 299 (KPN-Rt).
1 x E1 link b to PC 300 (KPN-Ut).
Both links have signalling on timeslot 16.
But that's only signalling.
The voice channels should be connected to PC 110 and PC 111.
This moring i discovered that the ISUP traffic from both PC 110 and PC
111 are received
through the signalling link on link a.
The lines on link a connected to PC 111 are Idle, and yesterday we even
had a succesfull call over it.
Bot the lines on link a are still in 'reset pending'.
What I see is:
Our side sends the GRS (reset) to PC 111 and PC 110.
Both answer with GRA (ack.), but incoming on link a.
The chan_ss7 looks up the CIC code from that link (link a).
For the GRA from PC 111, this is ok.
One step further (in process_isup_messages()).
The msg->opc is checked with the linkset->dpc.
And that's where it goes wrong. because the linkset (KPN-Rt) belonging
to link PC111, from the E1 link a) is 111.
And the GRA just received over that link has a source PC of 110.
By searching a little furhter...
In l4isup_event(), the ss7_chan is filled with the return value of find_pvt.
This only used the link and the CIC.
Because the CIC in my situation is for both links the same (1-15,17-31).
The find_pvt returns link a, because the CIC exists.
So I think we have two ways:
1) change something in chan_ss7 to return the correct channel (on
combined linkset) by supplying the peer PC to find_pvt
2) Or ask my local telco to change the CIC on PC 110 to 33-47,49-63
Oh, and in my config, Ignore the PC229 and PC300 links.
I just created them, so the PC110 en PC111 would get a SLS of 1 (PC229
an PC300 should have an sls of 0).
But the PC229 and PC300 are not linked to a zaptel span, because the
software only allows max. 1 link per span.
Thnx,
Robert
