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 somethingI'm in the process of doing the same thing for a friend's business that I have installed * for their
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.
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.
Specifically, I'd like to use a 4-port fxo sip gateway capable of supportingThe closest thing to your requirements that I am working with is an Audiocodes MP-104 or larger
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.)
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.
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)I think the Audiocodes MP-104 cost was around $1200 last year.
to accomidate those needs.
Anyone seen such a beast at a reasonable price?
