MediaTrix might have some too, perhaps sightly
cheaper, but they denied
shipping to us as we are not in their interoperability club (which makes
me cautios about their interoperability).
i bought one quite some time ago and they never fixed the sip bugs that
i found it in, so i had to return the box and ask my money back. i
don't know if the company or the product has become any better since
then. also, the box had a noisy fan.
i would recommend cisco ata if two analog ports are enough. its sip
implementation is the best what cisco has in any product and fixes have
been prompt.
