[Soekris] Asterisk on Net5501-70?

[K K]

Is anybody running Asterisk on a Net5501-70, any issues I should be
concerned about?

Idea would be to have everything come in over IPSEC, with a tunnel to
a SIP provider (e.g.Link2Voip), maybe 4 phones max.  Has anybody tried
the
Digium TDM403B in a 5501, it's a 4 port modular analog PCI 3.3/5.0V card?

I see articles about running  AstLinux on Soekris 4801, I'd hope the
newer platform should be sufficient., even with IPSEC overhead.
