Re: [asterisk-users] SIP Extensions and loss of Internet connection
A DNS cache on your asterisk box may be the answer.

Do your SIP extensions use your internal DNS server ? are they able to resolve the IP of your Asterisk server ? If you enable SIP debugging do you see them even try and connect ? The extensions have configured the Asterisk server by its IP, so I do not think there is a problem on that side. To enable debug I should use 'sip set debug'? from the Asterisk CLI? I do not see any record in the CLI after running this command. However, from Twinkle, for example, I see the following: - lun 10:49:59 Daniel, registration failed: 503 Service Unavailable - Thanks for your reply.

You have to be a bit more specific. For example is your Asterisk box behind a router/nat? Or does your asterisk box have two NICs one for the public and/or natted IP and one for the LAN? You need to specify your exact setup. I'm using Asterisk 1.4.24.1. I was researching on the Internet and I found that it can be related to a bug of chan_sip, can it be? In this case, is there a possible workaround? It's probably not a bug. Maybe you are registering by name and the name resolves to the public IP, and if you are in a DSL cable connection you public IP will change and perhaps you don't even have a public IP. Another possibility is that your ISP does not in fact give you public IPs (like most in the USA) and you have your LAN in the same network definition as theirs. I mean there are so many possibilities but you need to specifiy the exact network setup (IPs, masks, routing, etc.) Thanks in advance for your reply.

Re: [asterisk-users] SIP Extensions and loss of Internet connection
Hi, Alejandro. A few days I have problems connecting to the Internet on my house and since then my local SIP extensions are no longer registered against the local Asterisk server. You have to be a bit more specific. For example is your Asterisk box behind a router/nat? Or does your asterisk box have two NICs one for the public and/or natted IP and one for the LAN? You need to specify your exact setup. Asterisk is not behind the router. The problem I'm having is in the LAN. As I told Phil, I am experiencing the same problem both from a softphone on a workstation with fixed IP as a Grandstream phone (which gets network configuration via DHCP). In both extensions, the Asterisk server is configured with IP, so in that sense, I don't think the server is inaccessible to customers. On the other hand, I made sure to have commented in the sip.conf file any reference to providers such as Ekiga or iptel, so the server should not be trying to get to the Internet. It would appear that the server for some reason was 'locked'. For example, when I try to register from Twinkle softphone, I get the following: - lun 13:41:56 Daniel, registration failed: 503 Service Unavailable - Thanks for your reply.
