Hi List; Is there an Digium cards support GSM SIM cards so we can fix an SIM card to be used for calls within mobiles as it is less rate? Or I have to use an FXS to SIM adaptor? If yes, then anyone advise a models and prices?

I'll leave others to suggest models and prices, but in my experience, you're better with a SIP->GSM gateway and cutting out the analogue loop altogether. They're a bit more expensive, but it'll save you many hours playing with echo cancellation and gain settings on the FXS module.

Regards,

Chris

Check chan_mobile for bluetooth enabled phones. This is an extremely cool
app. The phone can be used as an FXO and/or an extension. You can also use
bluetooth headsets as FXSs.

AFAIR, the main limitation of it was that you could only use one device
per bluetooth adapter. Is this still the case?

But yes - cool indeed.

A few solutions - If you want to go down the analogue port route, then
this:

http://www.discountphonesystems.co.uk/acatalog/Analogue_GSM_Gateway.html

works well.

If you want to stay in the SIP/digital domain, then there are these too:

http://www.discountphonesystems.co.uk/acatalog/IP-GSM-Gateway.html

There are PCI cards which take 1-4 SIM cards, but I've not heard much
about them in the news recently, and last time I enquired, their price was
somewhat substantial... (However the lack of additional wiring, mains
plugs, etc. required may well be an advantage in their favour)

I'd presonally avoid any sort of bluetooth solution in anything resembling
a commercial environment. Give me a bit of wire, anyday!

Cheers,

Gordon

I don't think Digium do one, but Junghams (sp) do.

You don't have to have analogue loop. There are a number of GSM PCI
adapters, and all of them seem to have a separate signalling channel
between the GSM device and Asterisk.

For instance, the GSM support included in bristuff (used for the
Junghanns GSM adapter) sets each GSM port as an ISDN-like device with
just one B channel but still with one D channel.

AFAIK, both the Bero.net and the VoiSmart GSM devices are likewise
digital.

Gordon,

I am not sure if it has been included in chan_mobile yet but I remember talk
about adding direct USB connectivity to the code.

Anyways, GSM is wireless so I'd assume you would avoid this whole scenario.
Thanks,
Steve Totaro

You've asked for it:

P.S: you may have to solder the wire yourself :-p

Actually - er - a-ha - indeed... However the GSM part if it all is sort of
unavoidable !!! But I'd rather have a wire going from an asterisk box to a
phone device than use an additional wireless connection... I'm not sure
I'd get away with installing a box in a customers permises, then plug in a
USB/Bluetooth dongle, and then just leave a mobile-phone cable-tied to the
rack... At home/lab, sure. It's fun and neat, but not in the office where
even a USB cable from the server to the phone might be frowned upon. (The
phone would get nicked!)

I think what you need is a GSM Gateway You can find a cheap one at cyber-telecom.net The model you should be looking for is CT-G1000 or 2000 Plug the SIM in there and it will give you a RJ11 telephone port where you plug into something like X100P then you are ok to go..
