I'm trying to get work done and I start getting complaints that some of the inbound lines are down. After spending 10 minutes checking into it I see that voip.ms changed SOME of my DID #'s (without permission or notice) to Tampa & knocked them offline! WTF. FU voip.ms, F U
Let me guess - you run something based on asterisk and have dnsmgr turned off. Am I right? It's a typical example of user error.

When they moved the DID home to a different server (to Tampa), the device is still connected to the original server so the inbound call fails. The ip address on the A records for each server didn't change.
Maybe they should tell their customers before they start f*cking with their accounts. |

It's a typical example of user error. How often does Asterisk re-lookups a DNS entry for a server it's registering to? I'd think this would be based on the TTL for the DNS entry, is it not? |

I realize that, but if dnsmgr is turned off (it's off by default at least on some versions) - wouldn't Asterisk re-lookup a DNS entry after it's expired (TTL) anyway?? if not then that's a serious design flaw... |

No, it will not re-lookup! When dnsmgr is off asterisk does name resolution once and forever.

The whole point of having a TTL is to have lookups refreshed when they expire... oh well, good to know. What, in your opinion, would then be the point of the supposed dnsmgr?
It actually makes perfect sense when you think about it from the programming perspective: name resolution is only done when you load the config, so TTL plays no role whatsoever.
Basically, such a setup is only one step further from hardcoding IP-addresses by hand. A lot of system tools are designed like this (for one, firewalls come to mind, and ping, and ssh, and basically every other simple tool). |
