[asterisk-users] HA Asterisk

That's right.  By failover in this context just means making a connection to another box.  There is no detection of Asterisk hanging, missing registrations, no synchronization of mailboxes etc.  (So the word HA is a bit misleading)...

Xorcom makes a box that connects via USB that can do failover. You connect the box to the two system via a USB cable to each system. When the box detects the primary system fails it switches over the the second one. No need for any extra hardware, except a USB cable.

Hi Jim,

Thanks for sharing the technical details. Still not able to understand the setup. Let me explain what i understand is the 8 PRI line would be connected to the xorcom box and from there USB out would be connected to Primary Asterisk Server and Secondary Asterisk Server.

So we do not need any 8 port PRI Card on the  Primary Asterisk Server and Secondary Asterisk Server ?

Please correct me if i am wrong.

Thanks

Kaushal

Yes that's it - one PRI line in, 2 out (one to the PRI card in each server).  If you have lots of PRI lines, you may want to consider a dedicated PRI-to-SIP appliance..
Hi,

Thanks a Lot Michelle, Also please let me know the model/make for dedicated PRI-to-SIP appliance. Would appreciate if you can share the details along with the Network Diagram in case of 8 PRI Lines.

Much appreciated.

Regards,

Kaushal

Hi  Michelle

So what i understand is that the Single PRI Line from telco is connected to RJ45 (8 wire) A-B switched controllable by serial port and then there will be two patch cord from the A-B switch which will be connected to the 2 Asterisk Box containing PRI Card on each box.

Please let me know if i am understanding you correctly or if you can help me with Network Diagram that would be really helpful.
Also I have 8 PRI in my setup. How it would fit in this setup. The reason being we need to have atleast 320 Outbound Calls per min if i have 8 PRI Lines for our Voice Application.

Regards,

Kaushal
