There is a lot of good stuff posted on here on porting Asterisk, Freeswitch etc. But I'm not really sure what it enables in terms of use-cases. Would be very interested in that.

What we really need is some way to port a USB-RJ11 device for the plug so one could either receive call on their land lines and do stuff with incoming calls (digital answering machine and more..) or connect it to a phone to make voip calls, pstn calls or just to receive inbound calls.

I agree, especially since this thing is so energy efficient, it'd be great for this sort of thing.

Not knowing much about this stuff ... does this fxo device provide the dialtone for the analog phones attached to the PBX?

The device connects to regular POTS lines to provide connectivity to the traditional phone network. If you want to plug a regular analog phone into a voip network, you need an ATA (analog telephone adaptor).

A more elegant solution if you want to use regular analog phones would be this:

http://rowetel.com/ucasterisk/

It is an embedded device that runs Asterisk and can have either FXO of FXS modules installed (FXO is for phone lines, FXS is for phones). Uses about the same power as the Plug and is open hardware and software.

Shameless plug for myself, I wrote about it a little while back for LWN.net:

After much thought, I think the FXO/FXS interface should be included as part of the plug platform itself. Voice is a killer-app and the support for it should be native to the Plug. WiFi support would be great but not essential. Pricepoint of the plug even with the enhanced hardware should remain < $100 as they have it today.

But without native FXO/FXS support I just dont see the Plug really taking off as a PBX or VoIP phone. It becomes just too expensive to add any additional peripherals to it.

Just my Christmas 'wish list' I guess :-).

Thanks for asking.  It has been done.

http://www.silabs.com/products/voice/Pages/InternetTelephoneAdapterPlus.aspx

Silicon Labs developed the reference design to help them sell their chips.  Somehow Motorola got selected to build it.  I haven't been able to get anybody at Motorola to answer email about selling the product.

Here it is on their web site.

http://www.motorola.com/Business/US-EN/Business+Product+and+Services/Software+and+Applications/Software+Solutions/Communications+Software/Skype_Phone_Adapter_ITA_Plus_US-EN

They apparently want you to use it with the own version of the plug, an embedded system with a SOC, running what is probably a rebranded version of asterisk.

http://www.motorola.com/Business/US-EN/Business+Product+and+Services/Software+and+Applications/Software+Solutions/Communications+Software/Parlez+voice+gateway_US-EN

Maybe somebody can get Motorola to answer email.

Perhaps Marvell would like to kick some Silicon Labs butt by making their own SLIC chips.  But then again, chasing the analog telephone market seems like making electric buggy whips.

Move along, nothing to see here.

I agree, any external FXO/FXS supporting device just adds to complexity and cost thats not really worth it. From that standpoint I dont think using the plug as a VoIP server is going to be that useful thought it may have some niche uses. For mass market adoption it MUST be included within the plug itself.

My top three items on the wishlist for the plug:
* Native FXO/FXS interface
* WiFi : 802.11 a/g/n
* Additional USB/Firewire port
 
The combined device can sell for a $30 additional premium.

plugcrazy, I did see a plug with Wifi and two USB ports on it at Marvell's booth at CES.  Not sure what the status is re: releasing it as part of the dev kit.

yeah, its the plug 3.0 .  Not sure when it ships either. Some other discussions in the forums say Q3 2010.
But it still misses the FXO/FXS port, which I think would be a killer app. Ha

Why not use a Sipura3000 or SPA3102? I use SPA3102 myself connecting to asterisk running on the plug, it's got 1 FXS and 1 FXO.

I wonder if someone could modify a MagicJack for this... it's got RJ11 and USB. Would be really neat to have that running off an always-on plug...

I don't see why you could not modify a magicjack for this.  sounds like a good plan to me!
