[asterisk-users] Asterisk dies when external access is lost
Hello Looking for some help with a rather odd problem. We have Asterisk 1.4.10 running on a Linux box, within our Windows domain. Our Domain Controller is a Windows 2003 server, providing the normal Windows domain functions, such as DHCP and DNS. When we lose either our Domain Controller (for a reboot/maintenance) or external ADSL access, Asterisk drops all SIP registrations - even internal SIP calls within the building no longer function. All of our SIP clients are assigned static IP addresses, and our incoming lines are via a Zaptel card using (currently) analog lines from our national telco. When the SIP registrations drop, Asterisk will still answer incoming calls via the Zap channels, but can't forward them anywhere. What is most confusing is a recent issue when our ADSL connections were all offline, and despite everything internal to the network working perfectly, all of the SIP phones stopped working and left us without phones for 4 hours. I'm suspecting that these two issues (losing connectivity when DC is unavailable and losing connectivity when ADSL drops) are related, but I can't figure out how? I'm sure I'm missing something simple in the config, but I've been tinkering with this issue since we were using Asterisk 1.2 and I've still not resolved it. Any help or comments would be appreciated... Thanks in advance Phil Phil Knighton ___ -- 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

Not sure if it cures your problem but I would suggest running a caching nameserver on the Asterisk servers. http://lists.digium.com/pipermail/asterisk-users/2008-September/218764.html Philipp Kempgen -- http://www.das-asterisk-buch.de - http://www.the-asterisk-book.com Amooma GmbH - Bachstr. 126 - 56566 Neuwied - http://www.amooma.de Geschäftsführer: Stefan Wintermeyer, Handelsregister: Neuwied B14998 -- ___ -- 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
Re: [asterisk-users] Asterisk dies when external access is lost
just an idea, could it have something to do with DNS being unavailable, but that wouldn't really explain why it would die when ADSL is down... h.

Doug, No, the phones are all Snom phones - a mix of 290s (actually elmeg IP190), 320s and 360s. Mostly using firmware v6.

I had the same issue a few months back, internet connection went down, pointed the Polycom's to our internal DHCP/DNS and the phones failed. Turned out that our bind install wouldn't respond to the network that the phones were on (10.10.10.x). Since then, I've found how to make bind respond that that network segment as well and the phones are fine.
