This then happens to block all incoming LAN SIP traffic. Philipp No, it can not be this. I just adapted my fireawall-ruleset, my asterisk can not reach internet anymore (all registers fails), But i still can phone internally, or use the isdn-line.

Asterisk gets hung when it can't access your DNS server and all things grind to a halt (ie, phones can't register). The two things we make sure to do on any new installation is to: 1) use only IP addresses in all the config files. 2) set srvlookup = no in sip.conf. Try those 2 things out and then remove the internet connection from your server. Check and see if call processing works normally. If it doesn't, do a tcpdump or ngrep capture to see what DNS queries are being done and figure out why. I disagree. If you want to change an address, you have to change it on lots of places, and you allways forget one ir two. For maintenace purposes it a real PITA if people keep using addresses everywhere. There should only be _one_ place where addresses are used and that is in your _local_ name server. DHCP will ditribute realm and the address of you nameserver to any clients. If your bind is working properly (and that is something to take seriously) it just should works. Not only for asterisk, but for dhcp, mail, vpn, nfs, smb, apache, ldapm, iptables, kerberos and god knows what else. DNS is always the first thing that should work without a hitch, If possible with failover.

Re: [asterisk-users] Why asterisk down when inet server down?
Based on my somewhat similar experience a few times, when this happens, try to resolve an IP, to make sure there is a valid DNS server accessible to Asterisk. If not, either make asterisk a DNS as well, or remove any domain name entries from /etc/resolv file and replace them with the IP addresses of your DNS.

Re: [asterisk-users] Why asterisk down when inet server down?
Hi! But why can't my phones call. The outgoing lines are PRI/DAHDI T1. No sip. No iax. Why does the asterisk machine have to resolve any address? Probably because you have one or more register = statements in your sip.conf and Asterisk is trying badly - but without success - to register itself to one or more of your providers. This then happens to block all incoming LAN SIP traffic. Philipp -- _ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?

Cary Fitch The sip proxy server and the sip registrar server are both set to 10.10.10.180. sean Our company has set up hundreds of asterisk boxes over the years. One thing we learned early on was to avoid any type of DNS resolution by asterisk. Asterisk gets hung when it can't access your DNS server and all things grind to a halt (ie, phones can't register). The two things we make sure to do on any new installation is to: 1) use only IP addresses in all the config files. 2) set srvlookup = no in sip.conf. Try those 2 things out and then remove the internet connection from your server. Check and see if call processing works normally. If it doesn't, do a tcpdump or ngrep capture to see what DNS queries are being done and figure out why.
