Voip fail over device solutions, please help
Hi all, I am planning to deploy some test over a voip server, I'll be setting up two voip servers, but I want to know if there are devices that can take one T1/E1 PSTN lease and then transform that signal into IP and connect it to a ethernet card on each voip server. Also I'd like to know if I can do the same with the FXS analog phones which will be connected to a telphone patch panel and from that patch panel to a TDM 50pins PCI card, for example: 1- phone1<--->||Telephone ||<--Amphenolcable-->|Failover|<--->*1 phone2<--->||patch panel|| |device..|<--->*2 2- (*1-VOIP_SRV1)<--IP-->|Ethernet|<--TDMoE--->|Failover|<--->T1/E1 (*2-VOIP_SRV2)<--IP-->|Switch | |device | What are the best IP to analog phones PCI cards supported by Freeswitch, any hints?. Thanks in advanced for your help. Carlos.
Carlos, if what you want to achieve is to use a T1/E1 line that is remote, so not connected physically to your FS box, I think you need this: http://support.red-fone.com/index.php?_m=knowledgebase&_a=viewarticle&kbarti... There could be other vendors, I have absolutely no knowledge about this, I just found out about it recently. I don't even know if it works.

you can setup a pri card into the boxes and use isdnguard (from junghanns) or berofos (from beronet) to failover the main pri line to one of the boxes. for analog there're some similar solutions, but only for small ports numebers... mat
Looks like other folks have answered about PRI. You can in fact fail over large numbers of analog lines. Look for a power fail relay type device. I know that Dees Telecom makes some of these. They have 50 pin Centronics connectors on them, and can switch large numbers of circuits (all at the same time). Usually, these are triggered by loss of electrical power, so you may have to come up with a creative way to activate this device. If you can generate some sort of heartbeat signal on a serial or parallel port, that could be used. Alternately, there are some serial and Ethernet to contact closure interfaces (Adantech's ADAM line of industrial automation products) that could control the relays. You would have to write a script to generate the MODBUS commands that these use, but the protocol is well documented. If you used the Ethernet version, either box could issue a command to "switch to me". That is a little bit more expensive than making your own heartbeat detector, but it doesn't require any soldering. You can also use these boxes to give you status on things, and remotely reboot equipment. -Tim Matteo wrote:
