Hi list!
Running Asterisk 20.0.0 on CentOS 7, logging CDRs using
cdr_adaptive_odbc to mariadb-server-5.5.68 (via
mariadb-connector-odbc-3.1.7-ga-rhel7)
Using chan_sip.
I'm facing the problem when there is a sudden spike of calls, some of
the calls that are being made during those spikes hang forever
basically. This looks like this:
[root@voip]# asterisk -rx 'core show channels verbose' |sort -r -k 9 |
grep -v Outgoing
Channel Context ExtensionPrio State
Application Data CallerIDDuration
Accountcode PeerAccount BridgeID
SIP/customer01 customer-voipin 49xxx 26 RingDial
SIP/+49xxx@provider4912:49:05
So, the longest currently active call is in state "Ringing" for 12 hours
49 minutes.
It could be also that a call is in state "Up" for an arbitrary duration
(10, 15, 20+ hours). A cron script is restarting Asterisk every night,
and this is the moment these calls are cleared, otherwise they'd
hang/run forever.
Now, the problem is, that this is causing a billing discrepancy. I've
had calls with billsec 20+ hours and state "Up" in the CDRs. The
termination providers (there are multiple) are ending the calls after
max. 120 minutes, so the issue is not there but in the local Asterisk.
Any recommendations on how I could debug, or even fix, this?
Maybe a workaround to help with the billing discrepancy?
In theory, if I set TIMEOUT(absolute) to maybe 2 hours and 2 minutes, I
could find and delete those ghost calls in the CDRs at the end of the
month, before sending the invoice to the customer, but that's not a good
solution either (because losing money). But maybe still better than
overcharging the customer thousands of minutes?! :)
This behavior happens every day on approx. 5-200 calls. (At the end of a
day I could have 200 hanging/ghost calls).
Help! :)
Lastly, a "core show channel" on a hanging call, obfuscated:
[root@voip asterisk]# asterisk -rx 'core show channel
SIP/customer01-dfa4'
