Re: [asterisk-users] Asterisk load balancing and failover
About two years ago I setup two high availability solutions using DRBD and Heartbeat. The worked great and shutting down or unplugging one server stayed transparent for the callers, as IVRs stayed available. Having said this, it was not very straight forward to set it up, but not very difficut either. So Heartbeat and DRBD can be a good starting point for you. -- Zeeshan A Zakaria On 2010-03-26 4:40 AM, "huu giang" wrote: Hi List, I'm finding a solution to provide failover and load balancing features to my IVR system.

Re: [asterisk-users] Asterisk load balancing and failover
Hi Zeeshan I know a solution using DRBD, Heartbeat and RedFone hardware to provide failover ability to Asterisk. If I have two Asterisk Servers, and each server has a TDM card and a PRI line connect to each card, how your solution can provide failover ability to Asterisk ? Do you need any other hardware? The calles to my IVR System don't just come from IP network (SIP) but can come from SS7 network. Thanks. --- On Fri, 3/26/10, Zeeshan Zakaria wrote: From: Zeeshan Zakaria Subject: Re: [asterisk-users] Asterisk load balancing and failover To: "Asterisk Users Mailing List - Non-Commercial Discussion" Date: Friday, March 26, 2010, 1:51 AM About two years ago I setup two high availability solutions using DRBD and Heartbeat.

Unfortunately not. DRBD and Heartbeat solution is good for pure VoIP.

Re: [asterisk-users] Asterisk load balancing and failover
I'm not quite sure what do you mean with MSC. Anyway, I assume your environment is like [PSTN (Public Switched Telephone Network)]<-->[DTM Switch]<---SS7 (PRI line)>[Asterisk Box]<VoIP (SIP/IAX etc...)-> IP net If you mean MSC Mobile Switching Center it could look like [GSM Network]<->[MSC]<- SS7 >[Asterisk Box]<-VoIP-->IP net Normally, the DTM Switch or MSC should be configurable for load-balancing and failover.

Re: [asterisk-users] Asterisk load balancing and failover
As I Known, when a call coming to a MSC, the MSC will request the HLR for subscriber information. HLR response will include the address of the Asterisk Server, so the MSC will forward the call to Asterisk Server. Is it right ? If I have three Asterisk Server (each has a point code), is there any way to configure HLR so when MSC ask HLR about the Asterisk Server, HLR will response the address in a round robin way. So the call will be balance to three Asterisk Server ?. Do you mean above is the way MSC do load balancing ?. --- On Thu, 4/1/10, Ngo-Vi Hoai-Anh wrote: From: Ngo-Vi Hoai-Anh Subject: Re: [asterisk-users] Asterisk load balancing and failover To: "Asterisk Users Mailing List - Non-Commercial Discussion" Date: Thursday, April 1, 2010, 3:01 AM I'm not quite sure what do you mean with MSC.
