Thanks for the info. This little experiment is getting expensive ;-)
LOL! I know that feeling... I actually thought I would save money with
VOIP, what a joke! Actually I am happy with my setup, but spent an
intial $75(us) thinking the HT-488 would provide an FXO for my PSTN
connection, only to find it doesn't work well enough to actually use for
that.
I then spent an additional $200(us) for the Wellgate 3701a (1FXS+1FXO)
which, although horribly documented is a HUGE improvement over the
Grandstream garbage (HT-488).
So yeah, it gets expensive quickly. It's annoying that so many of the
products are marginal or straight up garbage, but I guess we are still
in the infancy of the standards based VOIP business, and many of the
products are in search of a firmware update, or a decent manual.
Oh well, More work for the stubborn techo-maniacs who refuse to give
up(like me).
I've gone through the same basic devices over the last three years, but
have also tested the Mediatrix 1204 box as well.
I've got four analog pstn lines here coming from two different central
offices, both of which are on relatively long loops with somewhat
unusual echo characteristics. I have also gone through the spa3000,
ht488, x100p's, multiple h/w versions of the TDM04b, etc. Also have a
TDM2400 here for testing, but testing has been held up due to delays in
being able to run current trunk code on the test machine.
To date, the best devices from a "quality of audio" perspective are the
Mediatrix 1204 and the Sangoma A200D. The last time I worked with the
1204 was about two years ago and the box had several compatibility and
security issues that hopefully have been resolved since then. Its retail
price is higher then the A200D (in the US). The A200D has been in use
now for several months and has provided excellent audio (etc), supports
modem use (fax and POS), and just hasn't failed in any way.
Rumor has it that Digium will be announcing some new cards in the near
future that should also help address the space for small numbers of
analog pstn lines. Unknown as to what the current status happens to be.
