[asterisk-users] No audio on Zap (T1/PRI) channels
I have 12 T1's going into 3 servers, 4 in each into "Digium, Inc. Wildcard TE410P Quad-Span togglable E1/T1/J1 card 3.3v (rev 02)" cards. Each "group" of T1's have the primary D on 24 and the secondary D on 96. The first server (ts20) and the last server (ts22) can playback "demo-congrats" fine. The "middle" server (ts21) cannot -- just dead air. If I call via ZAP, dead air. If I call via IAX, I hear the file. I copied /etc/zaptel.conf, /etc/asterisk/*, /var/lib/asterisk/sounds/demo-congrats.gsm from ts20 to ts21 -- no joy. I have seen this in my system log file: Oct 2 18:41:49 WARNING[7477]: chan_zap.c:8087 zt_pri_error: [Span 0 D-Channel 0] PRI: !! Got reject for frame 95, but we have nothing -- resetting! I'm running asterisk-1.2.24, asterisk-addons-1.2.7, libpri-1.2.5, zaptel-1.2.20.1.

From experience, I would say you crossed a couple of cables. Make sure you double check them and then LABEL them. If you find that is not the solution, call your provider.

I think this is the problem, or at least "a" problem.
When Qwest pointed a number to the group, I noticed that calls arrived on
ascending channel numbers. I observed...
Accepting call from '202239' to '866205' on channel 0/1, span 1
Executing Answer("Zap/1-1", "") in new stack
Subsequent calls show the following:
Channel SpanZap
0/1 1 1
.
.
.
0/231 23
1/1 1 73
.
.
.
1/231 95
2/1 1 25
.
.
.
2/241 48
3/1 1 49
.
.
.
3/241 72
So it looks to me like the T1 that is plugged into the second jack on the
card really belongs in the 4th jack. Can I fix this by munging my
configuration? (I'm in San Diego and the servers are in Phoenix.)
Here's my zaptel.conf:
#
# span 1
span= 1,1,0,esf,b8zs
bchan = 1-23
dchan = 24
#
# span 2
span= 2,0,0,esf,b8zs
bchan = 25-48
#
# span 3
span= 3,0,0,esf,b8zs
bchan = 49-72
#
# span 4
span= 4,2,0,esf,b8zs
bchan = 73-95
dchan = 96
#
# (end of /etc/zaptel.conf)
And my zapata.conf:
[trunkgroups]
trunkgroup = 1,24,96
spanmap = 1,1,0
spanmap = 2,1,2
spanmap = 3,1,3
spanmap = 4,1,1
[channels]
context = block-ani
echocancel = no
echocancelwhenbridged = no
echotraining= no
group = 1
resetinterval = never
signalling = pri_cpe
switchtype = dms100
; switchtype = 4ess
; span 1 (1-24)
channel = 1-23
; span 2 (25-48)
channel = 25-48
; span 3 (49-72)
channel = 49-72
; span 4 (73-96)
channel = 73-95
;
; (end of /etc/asterisk/zapata.conf)

I guess you could work around it by messing with your configuration and
changing channel numbers and putting your backup D on the correct
channels.
I would highly advise against it though. You should call someone in
Phoenix (just left there) and have them correct the cabling so it is
done the proper way. Even if you do get it working with the channels
all mangled out of order, it will bite you sometime down the road (or
someone else) when some sort of problem arises and you are trying to
troubleshoot it.

Qwest and I fiddled for a couple of hours. The channels are answered in ascending sequence and "match" between logical span/channel and zap/channel. Channels 0/24 (zap/24) and 1/24 (zap/48) are "skipped" because they are the primary and secondary D channels. Still no joy -- no audio.

This was with Global Crossing. There are only a handfull of combinations to try. I did not use a backup D chan as I figured if one D chan went down on a trunk group, both probably would so that adds to your mix. Just keep fiddling with spanmap and testing calls. If you can get your provider to point DID a did to each individual span, it will make troubleshooting much easier without needing a tech on the phone. This is how I solved my issue. From the wiki: spanmap => 1,1,3 spanmap => 2,1,1 spanmap => 3,2,2 spanmap => 4,2,0 When we had it configured 0,1,2,3 any calls that came into spans 1 or 2 worked fine. But spans 0 and 3 did not pass any audio. Switching the logical span numbers fixed it. This is because zapspan #1 is suppose to be the one that the D-Channel is on. In our case that was actually logical span 3. Be sure to watch out for this, we were confused and took up a few hours of a GBLX tech's time to get it fixed.

Yes, if you are running NFAS, getting dead air on a call is a symptom of not having the logical span identifier correctly corresponding to the physical span you have plugged in (spanmap option in zapata.conf, IIRC). -- Matthew Fredrickson Software/Firmware Engineer Digium, Inc. ___ --Bandwidth and Colocation Provided by http://www.api-digital.com-- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users

Success (finally). The spanmap that worked (of no value to anyone else) is: trunkgroup = 1,96,24 spanmap = 1,1,1 spanmap = 2,1,3 spanmap = 3,1,2 spanmap = 4,1,0 We were told (by Qwest) that the primary D channel was the 24th channel on the first T1 and the secondary D channel was on the 24th channel on the second T1. This turned out to be false. We even had the tech drop carrier on each T1 (one at a time) so we could identify which T1 was plugged into which port on the card. The "winning" strategy was to configure all 4 T1's as if they had a D channel and let Asterisk tell me which T1's actually had a "provisioned and up" D channel using the "pri show span x" command. The one that showed as "active" I made primary and "standby" as backup. Once I knew which physical channels were actually D's, setting up the trunkgroup was easy. When I placed a call, I got audio. I nearly fell off my chair. Then the next call was dead air. The first call landed on the last channel of a T1 and the next call was the first channel of the next T1. I tried to "logically" figure out which zapspan was which logicalspan, but in the end I cracked open a beer, made a table of the 26 permutations and stepped through them one by one. On my 13th try, I got an "order" that gave audio on all 96 channels. The morals of the story: ) Don't believe the tech if it conflicts with reality. ) Don't accept an NFAS trunk group until you have tested each and every channel.

I love that feeling when you are so frustrated you just want to quit or smash something and then suddenly you succeed! I like your troubleshooting strategy too, configure them all as if they had a D chan and the ones that come up are in fact Ds. So simple, yet I probably would not have thought of it. I would have just tried each configuration until it worked. You should update the wiki with your little nugget of troubleshooting NFAS wisdom.
