I'm scoping out HA for a relatively simple Office/Call Center PBX. Current setup uses a TE412P with 4 PRI our telco with SIP hard/soft phones for users. Some outbound also goes to a SIP provider.<br><br>Active/Active looks to be too much hassle for an installation this size, so we're looking at adding an extra * in an active/passive configuration with Linux-HA in between them.
<br><br>Does anyone have any experience using The Redfone Fonebridge2 in this configuration? It seems like it would do the trick, but I can only find the one testimonial/tutorial on <a href="http://voip-info.org">voip-info.org
</a>. Specifically, I'm wondering about the reliability of the device itself (since you can't seem to pair them in any way) as well as what extra work the * box has to do in a TDMoE configuration. I can't find any mention of EC being done on the Fonebridge, so I assume you'd have to use software echo cancellation in the zaptel driver. Other than the CPU to do that, does zaptel take up more/less CPU reading frames from a PCI card vs TDMoE?
<br><br>Any experience or suggestions on other ways to do this are appreciated.<br><br>-- <br>j.
