Re: [asterisk-users] ISP down internal phones become unavailable
Hi all, I have a PRI, and when the Internet connection goes out so do my phones. I suspect it is some type of DNS issue. I do have a SIP trunk, and it appears that if I lose DNS to the SIP trunk, the entire PBX is offline. I have no actual proof of any of this, and have not done any extensive testing to prove or disprove this. well, we have various asterisk installations, ranging from 1.4.25 to (upgraded today) 1.4.33 (we don't use 1.6.X yet) and two of them show this behaviour... one is upgraded to 1.4.33, the other is 1.4.30, they have similar configuration to all the other machines (which work flawlessy even when connection is down), and the phones are the same brand/model we use everywhere, with almost the same configuration. I'm not sure about a DNS issue because all our customers have local DNS/cache servers and we configure all the phones (and sip trunks on asterisks) with ip addresses and not FQDNs just to be sure... what we see is when the trunk goes down, i.e. 'Registration for ...@yy.yy.yy.yy timed out, trying again (Attempt #ZZ)' we have also 'Peer XXX is now UNREACHABLE (internal phones), even if they are pingable/accessibile on the LAN... -- _ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?

There must be something different in the configuration or DNS. However Asterisk should gracefully handle no DNS or a SIP provider issue without affecting the phones. I haven't been able to troubleshoot this much since I can't just take the Internet connection down. Ryan -- _ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?

[asterisk-users] ISP down internal phones become unavailable
I saw the following lines in the log this morning. From my router logs I see that the connection went down as my ISP was doing maintenance for a few minutes last night. I can understand the external registrations timing out, but why do the phones become unreachable. They are on the internal lan within the same subnet as the Asterisk server. Internal DHCP and DNS was functional. If I had a PRI card in this system as well that would mean I couldn't make phone calls because the Internet is down.
