You can build TDMoE units yourself based on cheap 1u or mini-itx enclosures since TDMoE can work with a low end CPU like a single 1GHz Via CPU.
It really makes a difference if you don't need onboard EC since you can get it for ~$600 for a quad port T1/E1 TDMoE while a quad port non-EC redfone is ~$1600 at voipsupply of course you would have to put some configuring effort into this Martin On Fri, Oct 2, 2009 at 11:55 AM, Mitul Limbani <[email protected]> wrote: > Hello, > > I woud recommend using quad red fone devices over 1gbps Ethernet, all > on 1U servers with dual NICs and since there is no on machine irq > used, you can do away with lesser powerful boxes. > > You can also look at HA with ultramonkey heartbeat, to ensure > avolability in mission critical situations. > > If you need any setup n confg help we can provide the same. > > Thanks & Regards, > Mitul Limbani, > Founder & CEO, > Enterux Solutions Pvt.
