asterisk users - Feb 2004 - Still looking for small fxo sip gateway

I've been looking around for a small external sip fxo gateway, sending
emails to possible vendors, etc, and can not seem to come up with anything
that fits. Suggestions anyone? (No channel bank & T1 card suggestions, 
please. I've also just completed an eval of the Mediatrix 1204 which
does not support the requirements.)

The market between two fxo pstn lines (pair of x100p's) and something
around four to six lines seems to be lacking, or I'm looking in the
wrong search engine (or something). I fully understand the economics of
when a channel bank and T1 card becomes cost effective, including the 
eBay costs (and risks), etc. I've also heard the comments for months 
now that Digium is/will be selling something real-soon-now.

Specifically, I'd like to use a 4-port fxo sip gateway capable of supporting
four US pstn analog lines, CallerID, Touchtone, loop style supervision,
and have the capability for asterisk to direct an outbound call to a 
specific port on that gateway. I "think" that implies "each"
port must
execute a sip register command successfully. It's also expected to accept 
incoming pstn calls directing those to a single asterisk. (I don't care 
about an IP dialtone, nat, etc, just a plain-jane two-way sip gateway.)

If anyone is designing such a box and need professional eval, we can 
certainly work with you privately (off list to radamson @ routers dot com)
to accomidate those needs.

Anyone seen such a beast at a reasonable price?

You might want to take a look on the Wiki pages for VoIP, in particular:

http://www.voip-info.org/wiki-VoIP+Gateways

Offhand at our site we're trying to set up something similar (although a
little larger, 10 FXO lines, but no requirement to pick which line the call
goes out... our 10 lines are all overlines....).  Our Vegastream 50 FXO
shipped yesterday (or perhaps this morning), so we should be getting it in a
day or two.  (BTW: I'm in Canada)

There's been rumours posted to this list that Digium is coming out with a
higher-density FXO card, and Woody mentioned a Voicetronix Openline12, which
appears to be a 12-port FXO card.  And I believe that Intel/Dialogic puts
out some multiport FXS/FXO cards...

Rich -
   No.  :-)  However, you might consider Welltech ( 
http://www.welltech.com.tw/) to see if you can demo their products - 
they have a SIP load now for some of their boxes.  Website currently 
offline, but I think that's just a network error not a "company" 
error.

I second that.  Mediatrix is not RFC3261 compliant.

I'm in the process of doing the same thing for a friend's business that 
I have installed * for their
PBX solution.  I work for a company that develops SIP based technologies 
for carriers so the
gateways are extremely expensive but "work".  What I have found is
that
these SOHO type
gateways are very unstable, non-standard and/or lacking in basic features.

The closest thing to your requirements that I am working with is an 
Audiocodes MP-104 or larger
gateway.  My friend bought a MP-104 and it has 4-ports that we have 
configured for FXO.  It
has Caller-ID, hunt-groups in any combination of the ports.  The only 
problem that I am having
with it is DTMF relay, which I will hopefully resolve with their latest 
firmware load.

SIP gateways normally do NOT register.  Some smaller ones may but this 
does not scale.  Imagine
a bunch of 24-port FXO gateways all registering at once!  You normally 
just set the "proxy" on the
gateway, give each port an "ID" and on the PBX/proxy have a routing
rule
that goes out via the
gateway.

I think the Audiocodes MP-104 cost was around $1200 last year.
