I highly suggest you don't use TDMoE. Especially not if you are
purchasing new equipment, much less if you use Kernel 2.6. TDMoE is
depreciated there has been no recent development and while its not
unstable it seems to be an interrupt hog on Kernel 2.6, at least
recent versions.

The ISDNguard is about USD 650... Another option could be a PRI SIP
gateway you just need to make sure you can integrate fail over with
it.
