Description:Based on the every 20 minutes, I'm guessing its occurring during the reregistration; so, the category may be incorrect. I have no zaptel devices and am using Dahdi dummy.

I checked through the asterisk logs and found nothing with verbose 99 pertaining to that device other than registrations.


Running CentOS fully updated (including kernel) from Centos repository.

Asterisk was configured with default options.

Per bug reporting guidelines, we need SIP debug and console output.

I will gladly send you the faulty device so you may use it to try to make asterisk more stable in any of these cases.

I will add the device back to the network and post anything related to it with sip debugging later but, at the moment, I can't afford a lockup.

Setting this to feedback while we await the reporter to provide some information that allows us to move this forward.

Whatever the bad device is doing, asterisk is locking up the system before showing what was sent from the device in the console with "sip debug ip (deviceip)"

doesn't appear in the log either

In that case, it's probably best to obtain a packet dump, with tcpdump or wireshark.

@johnakabean: just a suggestion, you might want to use tcpdump(8) to capture SIP exchange with the device.

Can you try:  session-timers=refuse

And see if that helps at all? This is just a weird hunch for some reason based on some other bug reports.

Closed due to lack of feedback. If the reporter is able to provide the requested information, please reopen this issue. Thanks!
