Hi Matthew Ok, I have added some extra logs in the libss7 source code and tried to debug it. First of all, the version of libss7 is libss7 version: SVN-mattf-bug13495-r249M and the version of asterisk is Asterisk SVN-mattf-bug13495-r167584M built by root on a x86_64 running Linux on 2009-01-20 18:44:42 UTC
I don't know if anything drastic changed since. >From what I saw from the logs is, even if we log ' MTP2 link up', it is really not because we never see Adjacent SP PC: %i UP!!! And because we don't see that, adj_sp->state is still MTP3_DOWN. And because it is down, link_available always returns false, then rl_to_link returns NULL and we cannot pick a winner while transmitting with mtp3_transmit. As you can see : (adj_sp->tra & GOT) is still 0. And it looks like we never receive the TRA message. So, what does that message do and why asterisk is not seeing the SS7 link to be up when the telco is seeing it ? So : XXX mtp3_transmit:1730 , userpart 2, routing_label(type 2, dpc 113663, opc 345384 ) XXX mtp3_transmit:1741 userpart 2, winner = 0x7f7eac0b1ce0, ss7->switchtype 2 MTP2 link up XXX mtp3_transmit:1730 , userpart 2, routing_label(type 2, dpc 113662, opc 345384 ) XXX mtp3_transmit:1741 userpart 2, winner = 0x7f7eac045bc0, ss7->switchtype 2 MTP2 link up XXX mtp3_transmit:1730 , userpart 2, routing_label(type 2, dpc 113663, opc 345384 ) XXX mtp3_transmit:1741 userpart 2, winner = 0x7f7eac0b1ce0, ss7->switchtype 2 XXX mtp3_transmit:1730 , userpart 2, routing_label(type 2, dpc 113662, opc 345384 ) XXX mtp3_transmit:1741 userpart 2, winner = 0x7f7eac045bc0, ss7->switchtype 2 XXXXX mtp3_init:706 XXXXX mtp3_init:706 XXX mtp3_transmit:1730 , userpart 0, routing_label(type 2, dpc 113663, opc 345384 ) XXX mtp3_transmit:1741 userpart 0, winner = 0x7f7eac0b1ce0, ss7->switchtype 2 XXXXX mtp3_check:675 count = 1 XXXXX mtp3_check:675 count = 1 mtp3_check:693, count 1, adj_sp->state 0, adj_sp->tra 2 GOT 0 SENT 2 mtp3_check:693, count 1, adj_sp->state 0, adj_sp->tra 2 GOT 0 SENT 2 XXXXX mtp3_init:706 XXXXX mtp3_init:706 XXX mtp3_transmit:1730 , userpart 0, routing_label(type 2, dpc 113662, opc 345384 ) XXX mtp3_transmit:1741 userpart 0, winner = 0x7f7eac045bc0, ss7->switchtype 2 XXXXX mtp3_check:675 count = 1 XXXXX mtp3_check:675 count = 1 mtp3_check:693, count 1, adj_sp->state 0, adj_sp->tra 2 GOT 0 SENT 2 mtp3_check:693, count 1, adj_sp->state 0, adj_sp->tra 2 GOT 0 SENT 2 -----Original Message----- From: asterisk-ss7-boun...@lists.digium.com [mailto:asterisk-ss7-boun...@lists.digium.com] On Behalf Of Matthew Fredrickson Sent: Wednesday, February 04, 2009 12:13 AM To: asterisk-ss7@lists.digium.com Subject: Re: [asterisk-ss7] No siganlling link available sending message Ruddy Gbaguidi wrote: > Hi all > > I'm still having trouble getting my SS7 links up. > > [Feb 3 13:05:57] ERROR[3575]: chan_dahdi.c:11287 dahdi_ss7_error: No > siganlling link available sending message! > > [Feb 3 13:05:57] WARNING[3575]: chan_dahdi.c:11246 dahdi_ss7_call_null: > libss7 asked set to NULL ss7 call on CIC 4001 DPC 16093235 > > [Feb 3 13:05:57] ERROR[3575]: chan_dahdi.c:11287 dahdi_ss7_error: > Unable to send UBA to DPC: 16093235 Hey Ruddy, Sorry for the long delay, I have been kept extremely busy on a few different projects here at work.
