Re: [Asterisk-Users] looking for failover ideas
Can you post or email your patch can I take a look at it? It's specifically the issue of NATD that I'd like to be able to know what asterisk host a phone registers to. that way I can do an asterisk to asterisk transfer and the original asterisk host that the phone is registered to can pass the call back down the NATD connection. -bill I was going to add into Asterisk Realtime an extra field that is a server identifier.

We are building asterisk clusters using mysql replication. All the configuration and cdr data is stored using the res_mysql module. Replication creates identical servers. Then, the phones register to each server using DNS SRV records. If any server goes down, all the phones registered to that server will register to any of the remaining servers. The only downside of this is that all active calls get dropped once the server goes down, but users can make and receive new calls instantaneously. Another idea is to use Asterisk Realtime so that the mysql replication will share registration information between servers, thus eliminating the need for the phones to re-register.

Re: [Asterisk-Users] looking for failover ideas
I have had an idea of using two identical servers: Server A with IP x.x.x.a and server B with IP x.x.x.b. Server A is live while server B sits in the background monitoring server A. Server B rsync's asterisk config files daily with server A. In the event of server A going down, server B changes it's IP to x.x.x.a. The calls will obviously drop, but should register with server B.

RE: [Asterisk-Users] looking for failover ideas
We're currently working on a SIP load-balancing system using ipvsadm and so far it seems to work pretty well. We load balance the port 5060 registration (tracking the connection for a little more time than the registration retry so that it goes back to the same server) using tunneling. So a packet generated from a client is sent to the load balanced IP (ex. 192.168.1.100) the load balancer sees it as a new connection and sends it to the server with the least amount of connections (Ex. 192.168.1.103). 192.168.1.103 received the packet on it's tunnel interface. Answers back directly to the client (as coming from 192.168.1.100). Client answers back to 192.168.1.100 and gets sent to the same server. The actual RTP is not load-balanced and passes directly between client and real server. If I recall there was a little piece of magic with iptables to DNAT (because asterisk answered as coming from the real server... I'll have to check what it was.. Going from memory here) This seems to work well for the moment (using 1.0.9). Each server has all the devices configured and when someone calls for a specific device, we dial the device on our own server and call the device on the other server (special inter-server context) On the load-balancing machine, there is a monitoring (for the moment, just testing the port) on the asterisk service and on the pingability of the server using mon. If one of the servers goes down, it is automatically taken out of the load-balancer. Balances the load, and provides failover (using heartbeat for failover of the load-balancing machine. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Garth van Sittert Sent: August 23, 2005 1:58 PM To: [EMAIL PROTECTED]; Asterisk Users Mailing List - Non-Commercial Discussion Subject: Re: [Asterisk-Users] looking for failover ideas I have had an idea of using two identical servers: Server A with IP x.x.x.a and server B with IP x.x.x.b.

Re: [Asterisk-Users] looking for failover ideas
I'm looking at doing something very similar. I was going to add into Asterisk Realtime an extra field that is a server identifier. For example to allow multiple asterisk machines to use the same CDR DB. You would be able to select on the data from just one of the servers. Also for example in sip.conf for registration. Have the specific asterisk server that processes the sip registration put it's identifier (IP address for example) into a field in the DB also. That way other asterisk servers sharing the DB would be able to know what asterisk server a SIP phone is registered to. Does anybody else think this might be useful? Where would be the best place to have a server identifier variable? asterisk.conf? within the sip.conf that applies just to the sip SQL tables? -bill On 23-Aug-05, at 1:28 PM, Anish Basu wrote: We are building asterisk clusters using mysql replication.
