asterisk-app-queue causes a crash of asterisk

[fedv-mbu]

Maintainer: @jslachta

Environment: OpenWRT 23.05.3 on Zyxel NBG6716 ath79 / mips_24kc

Description:

I Installed OpenWRT 23.05.3 with Asterisk 20 on a Zyxel NBG6716 Router with all my other required modules for asterisk.
So far everything works great, except app_queue.

The Issue is as follows:
I dial my Queue test number which forwards the call to a queue called "zentrale"
The Member from this queue "6002" picks up
Asterisk Crashes with a SIGSEGV:

[ 4168.760322] do_page_fault(): sending SIGSEGV to asterisk for invalid read access from 00000001
[ 4168.769157] epc = 77356b3c in libc.so.6[772b0000+1b3000]
[ 4168.774603] ra = 77873ced in libjansson.so.4.14.0[77870000+9000]

Any Idea what might be the cause?
Things I've tried:

Different OpenWRT version (22)
Different Asterisk version (18)
PJSIP instead of chan_sip

Thanks!
Michel

Hi there, Can you post a simple asterisk config to reproduce this?

[fedv-mbu]

Hi There,

Here's my pjsip.conf:

;===============TRANSPORT

[simpletrans]
type=transport
protocol=udp
bind=0.0.0.0

;===============EXTENSION 6001

[6001]
type=endpoint
context=default
disallow=all
allow=ulaw
auth=auth6001
aors=6001

[auth6001]
type=auth
auth_type=userpass
password=6001
username=6001

[6001]
type=aor
max_contacts=10


;===============EXTENSION 6002

[6002]
type=endpoint
context=default
disallow=all
allow=ulaw
auth=auth6002
aors=6002

[auth6002]
type=auth
auth_type=userpass
password=6002
username=6002

[6002]
type=aor
max_contacts=10

And here's my extensions.conf: (The part that gets run)

[default]
exten => 6001,hint,SIP/6001
exten => 6002,hint,SIP/6002
include => vod-in
exten => 425,1,Answer
exten => 425,n,Wait(1)
exten => 425,n(rwlqueue),Noop(Zentrale an Warteschlange)
exten => 425,n,Goto(queue,zentrale,1)

And of course my queues.conf:

[zentrale]
;music = default
strategy = ringall
servicelevel = 30
timeout = 120
wrapuptime=5
announce = /mnt/usb/ansagen/ansage21
announce-frequency = 30
;announce-holdtime = no

;member => Local/zentrale1@default
member => SIP/6002

Hi there,

I tried your config. Only changed the "announce" in queues.conf and pointed it to a wav file that exists on my router. Upon start these are the logs:

Then I register two phones, 6001 and 6002. Then I call 425 and I only see this in the log:

Sat May 4 11:56:02 2024 daemon.info asterisk[4831]: [May 4 09:56:02] WARNING[4901][C-00000001]: pbx.c:4507 __ast_pbx_run: Channel 'PJSIP/6001-00000000' sent to invalid extension but no invalid handler: context,exten,priority=queue,zentrale,1

Asterisk didn't crash, but the call didn't work either. I guess something is missing in the reproducer. Please double-check and let me know what's missing.

[fedv-mbu]

Sorry, you're missing this context in extensions.conf:

[queue]
; Zentrale -0
; 30 Sekunden Announcement fehlt
exten => zentrale,1,Answer
exten => zentrale,n,Wait(2)
exten => zentrale,n,Playback(/mnt/usb/ansagen/ansage11)
exten => zentrale,n,Queue(zentrale,tT,,120)
exten => zentrale,n,Playback(/mnt/usb/ansagen/ansage12)
exten => zentrale,n,Voicemail(98,s)

[micmac1]

Now I can call extension 425 and get played the audio file. Nothing else happens.

[fedv-mbu]

Does the other extension not ring?
You need to dial from 6001, so 6002 as a queue member rings.
And pickup is where it crashes.

[micmac1]

Yes, that's what I'm doing. I got 6001 & 6002 registered to asterisk. Then I call 425 from 6001. This call leg gets answered, my wave gets played. That's it. 6002 doesn't get notified. Maybe missing some config still, or maybe a missing module. I don't know.

I misspoke, previous entry corrected.
