[Asterisk-Users] Vonage, PSTN, 911, and hardware question

Sat Oct 9 11:56:47 MST 2004

I stand corrected, according to Grandstream the POTS connecton can only be
used for a failover.

Subject: Re: [Asterisk-Users] Vonage, PSTN, 911, and hardware question

Thanks for the clarification. $377 still seems a little much to me. However,
I noticed this on 
voip-info on the * hardware page:
"# Intel modem marked with chipset 537 or MD3200. This card installs and
behaves exactly like a 
Digium Wildcard X101P card."

I searched froogle, and found a modem with an "Intel (Ambient) MD3200 soft
modem chipset" for $6.45:
http://store.yahoo.com/store4pc/in56kv92pcid.html
So, would I be able to use 3 of these modems with the X100P drivers? $20 is
definitely in my budget. :D

Also, about the Vonage ATA: which configuration is better? The only reason I
can see for using the 
ATA is avoiding problems with QoS and NAT, but I don't know much about his
stuff.

And, back to this question:

2. Phone availibility during a power outage is a big concern. I'm planning
on keeping my regular 
PSTN line around for emergencies and 911 dialing (so that 911 calls actually
go to the 911 center, 
along with my address). Is there an easy way for all the phone jacks in my
house to automatically be 
switched to the PSTN line if my broadband goes out? I'm also planning on
hacking together a powered 
switch so that when the computer's power supply goes down, the line gets
switched fully to the PSTN 
line, but I'm hoping somebody can give me a better solution.

Anybody have any suggestions about this?
