Harald Welte d08247b27d sccp_routing: add missing check_and_dec_hopctr() default case 2013-07-14 19:44:36 +02:00
Harald Welte ffc25358e4 routing: handle routing of incoming cr/connless by GT (not SSN) 2013-07-14 19:40:02 +02:00
Harald Welte 0b9cae1e91 SCRC: don't use tracing for this process anymore, reduce screen clutter 2013-07-14 19:32:08 +02:00
Harald Welte 54b54e8461 osmo_sccp_tcap: remove debug print 2013-06-24 12:24:04 +02:00
Harald Welte d9b9aaa9cd support local_out messages with GT but not pointcode 
We cannot determine the MTP3 DPC from simply looking at the CalledParty
GT address, as there is no PC in the GT.  We have to use the result
of the routing decision as MTP3 DPC in this case!

Harald Welte f6259f4ff4 osmo_sccp_tcap fixes 
* Ignore + Print N-NOTICE.ind from SCCP

Harald Welte e698ae2b4c SCCP: Make sure connection oriented messages end up with the user 
The user initiating the connection should get all messages related to
that connection, not the supervisor ;)

Harald Welte 9760efc644 SCPC: Make sure connection-oriented SCCP actually works 
This is a major patch that brings SCCP SCOC from 'should theoretically
work' to 'has actaully been tested to some extent for locally-originated
connections'

Harald Welte 67afe0b59a scrc: gracefully handle the case where local subsystem is unequipped 
sccp_routing will have responded accordingly, we simply ignore the
message in scrc.

Harald Welte abf1603e5c scrc: add FIXMEs about routing outgoing connection oriented msgs 
When we receive local-out messages from SCOC into SCRC, they need to be
SCCP-encoded, routed and MTP3-encoded before they can be passed on.

Spotted by dialyzer.

Harald Welte e75dff8b69 SCRC: deal with gen_server:cast() from MTP3 even though we're gen_fsm 2011-10-19 22:58:26 +02:00
Harald Welte ab725b5cc7 allow users to bind to a subsystem number on all local point codes 
binding to {SSN,undefined} basically corresponds to binding to a
UDP port with INADDR_ANY.

Harald Welte ab61a4ec38 complete SCCP routing code 
we now use ss7_links in order to determine which point codes are local
or not, and we use the routing table to determine the signalling link.

local-out routing form N-UNITDATA.req to the actual MTP3 on the correct
signalling link is now working.
