[Asterisk-Users] PSTN to VoIP FXO gateways?

2005-01-03 Thread Damon Estep
Sure would like to hear experiences using various FXO to VoIP gateways
with *. It seems that any thread that has anything to do with
problematic FXO interfaces goes on forever with speculation about
everything under the sun. Unless there is someone out there with the
engineering experience to build a better one it is a waste of time, let
Digium deal with it. If the TDM400P can ever be made 99.99% reliable it
will be a great product and I will gladly buy them.

Now, what DOES work? Channel banks are a little pricey when you consider
the need for PRI interfaces to * to use them. The solution seems to be
inexpensive FXO  VoIP Media Gateways, but there are only a few out
there and fewer reports of using them with *. If you use one please
share your experience!

Thanks

[Asterisk-Users] PSTN to VoIP

2005-01-03 Thread David Ishmael








Im about to purchase an adaptor for a POTS data modem
and was looking at the Sipura line of adaptors (SPA-1000, SPA-1001, SPA-2000,
SPA-3000). Do these work well? Anyone have a suggestion on which model of the
Sipura I should get? Does one work better with * than the others? Are there
other adaptors that work better that I should get?





Thanks,

-Dave

The Sipura's work really well and are highly configurable.

If you just want to connect a regular POTS device via VoIP the SPA-1000
will do the trick. The 2000 has 2 ports instead of 1, for a
less-than-double increase in price. The SPA-3000 has one FXS port but also
has an FXO port so you can connect a phone line to it too, as well as a
regular POTS device. Could be handy for analog connectivity?

Has anybody tried the Clipcomm CG-410? I am considering getting one but
would like to know if anyone has any good/bad experiences with it?

the spa 1k and 2k serve to connect an analog handset to ethernet
Not sure about pots.
The 3K series may have an fxo side which connects to the phone line,
but not sure about that
