Kaloyan, I really appreciate your consideration and help. I tried swapping the sigchans 109 with 140. But then this 4th link didnt come up. I dont have extra hardware to verify 8 sigchans in lab. I believe we are good. This seems provider end issue. Provider claimed to have 8 links configured. Can you point me how can we verify number of signalling links configured without their help? -- regards, abdul basit On Tue, Mar 27, 2012 at 7:27 PM, Kaloyan Kovachev <kkovachev at varna.net>wrote: > On Tue, 27 Mar 2012 19:00:53 +0500, Abdul Basit <basit.engg at gmail.com> > wrote: > > Here is the trail > > > > #dahdi_cfg -vvvt | grep MTP2 > > > > DAHDI Tools Version - 2.3.0 > > Channel 16: MTP2 (Default) (Echo Canceler: none) (Slaves: 16) > > Channel 47: MTP2 (Default) (Echo Canceler: none) (Slaves: 47) > > Channel 78: MTP2 (Default) (Echo Canceler: none) (Slaves: 78) > > Channel 109: MTP2 (Default) (Echo Canceler: none) (Slaves: 109) > > Channel 140: MTP2 (Default) (Echo Canceler: none) (Slaves: 140) > > Channel 171: MTP2 (Default) (Echo Canceler: none) (Slaves: 171) > > Channel 202: MTP2 (Default) (Echo Canceler: none) (Slaves: 202) > > Channel 233: MTP2 (Default) (Echo Canceler: none) (Slaves: 233) > > > > > > Sets up 248 channels to configure. > > > > This may help. > > I am afraid i can't help much from here - the channel is configured, but > Asterisk can't find it, which is weird. > > last idea ... if you replace one of the old sigchans (e.g. 109) with 140 > does it work? > > > > > -- > > regards, > > > > abdul basit > > > > > > > > > > On Tue, Mar 27, 2012 at 6:01 PM, Kaloyan Kovachev > > <kkovachev at varna.net>wrote: > > > >> On Tue, 27 Mar 2012 17:35:34 +0500, Abdul Basit <basit.engg at gmail.com> > >> wrote: > >> > yap. > >> > here is my system.conf: > >> > > >> > # > >> > # Global data > >> > > >> > loadzone = us > >> > defaultzone = us > >> > > >> > # Span 1: TE4/0/1 "T4XXP (PCI) Card 0 Span 1" (MASTER) HDB3/CCS > >> > span=1,1,0,ccs,hdb3 > >> > bchan=1-15,17-31 > >> > mtp2=16 > >> > echocanceller=mg2,1-15,17-31 > >> > > >> > # Span 2: TE4/0/2 "T4XXP (PCI) Card 0 Span 2" HDB3/CCS > >> > span=2,2,0,ccs,hdb3 > >> > bchan=32-46,48-62 > >> > mtp2=47 > >> > echocanceller=mg2,32-46,48-62 > >> > > >> > # Span 3: TE4/0/3 "T4XXP (PCI) Card 0 Span 3" HDB3/CCS > >> > span=3,3,0,ccs,hdb3 > >> > bchan=63-77,79-93 > >> > mtp2=78 > >> > echocanceller=mg2,63-77,79-93 > >> > > >> > # Span 4: TE4/0/4 "T4XXP (PCI) Card 0 Span 4" HDB3/CCS > >> > span=4,4,0,ccs,hdb3 > >> > bchan=94-108,110-124 > >> > mtp2=109 > >> > echocanceller=mg2,94-108,110-124 > >> > > >> > # Span 5: TE4/1/1 "T4XXP (PCI) Card 1 Span 1" HDB3/CCS > >> > span=5,5,0,ccs,hdb3 > >> > bchan=125-139,141-155 > >> > mtp2=140 > >> > echocanceller=mg2,125-139,141-155 > >> > > >> > # Span 6: TE4/1/2 "T4XXP (PCI) Card 1 Span 2" HDB3/CCS > >> > span=6,6,0,ccs,hdb3 > >> > bchan=156-170,172-186 > >> > mtp2=171 > >> > echocanceller=mg2,156-170,172-186 > >> > > >> > # Span 7: TE4/1/3 "T4XXP (PCI) Card 1 Span 3" HDB3/CCS > >> > span=7,7,0,ccs,hdb3 > >> > bchan=187-201,203-217 > >> > mtp2=202 > >> > echocanceller=mg2,187-201,203-217 > >> > > >> > # Span 8: TE4/1/4 "T4XXP (PCI) Card 1 Span 4" HDB3/CCS > >> > span=8,8,0,ccs,hdb3 > >> > bchan=218-232,234-248 > >> > mtp2=233 > >> > echocanceller=mg2,218-232,234-248 > >> > > >> > -- > >> > regards, > >> > > >> > abdul basit > >> > > >> > > >> > On Tue, Mar 27, 2012 at 12:46 PM, Kaloyan Kovachev > >> > <kkovachev at varna.net>wrote: > >> > > >> >> Hi, > >> >> > >> >> On Mon, 26 Mar 2012 20:18:48 +0500, Abdul Basit > <basit.engg at gmail.com> > >> >> wrote: > >> >> > I recompiled libss7 and asterisk with > >> >> > > >> >> > libss7-1.0.2/ss7_internal.h:#define SS7_MAX_LINKS 16 > >> >> > > >> >> > asterisk-1.6.2.10/channels/chan_dahdi.c:#define NUM_DCHANS 16 > >> >> > > >> >> > But as soon as i add 5th link, i get error > >> >> > > >> >> > Command 'module load chan_dahdi.so' failed. > >> >> > [Mar 21 16:25:28] ERROR[10641]: chan_dahdi.c:15568 > >> linkset_addsigchan: > >> >> > Unable to open SS7 sigchan 140 (No such device or address) > >> >> > >> > >> sigchan 140 is not found at all, which is outside of asterisk/libss7, > but > >> dahdi does not place such limits (1024 is far more than 16) > >> > >> what does dahdi_cfg -vvt say?
