mobile phone based switchboard

b0b

We have construction sites which we are regularly setting up with site
cabins, telecoms equipment, broadband, etc.

Occasionally phone lines, whether isdn or analogue take a long time to get
put into place either due to capacity at the exchange, new lines needing to
be run or simply where economics dont allow us to put lines in place.

Is there a switchboard based on mobile phone sims that I could put in place
in these situations ... something like a multi line premicell with basic
call transfer, fax capability, etc.

I dont know, but couldn't you just connect GSM gateway devices
to the POTS trunks of an ordinary system?

There are certainly "mobile phone" units that have a normal telephone
connection so could be used to feed a switchboard. I have seen one used
to connect a PMR (actually an emergency service) base station back to
their central control - it has been quite common to feed remote PMR base
stations using a PSTN connection if they do not carry a lot of traffic,
this one could not get a telephone line so used a "mobile phone"
connection.

Thanks both .... I've just found these ones:-

http://www.discountphonesystems.co.u...N2e__BRI_.html

Thinking we could use upto 4 of these devices for our isdn2e enabled pbx's.

I'm thinking they could be used in place of isdn2e or after costing it all
up if its more expensive to have the gsm gateways in use for all calls then
they can at least get the site up and running immediately with no telecoms
delays.

Certainly for the shoter term sites likely to use them exclusively ....
again, its a cost analysis needed to confirm it but the main concern is to
get a site up and running as quickly as possible and currently its taking
too long - the grey area savings from getting a site up and running quickly
are highly likely to far exceed any differences in call charges between land
lines and mobiles ... in fact its starting to become more calls to mobiles
than to landlines these days too.

Hi Bob

I may well be able to help you out with this, as I spe******e in these
devices plus the sims to go into them (see my ebay shop
simonclarkbusiness for particular examples only).

If you wish to discuss further, my email is my full name with no dot
at my business name dot com.

Regards

Hi Bob,

You should find that Fixed Cellular Terminals (aka Premicell devices)
work fine in this manner - just attach them to analogue trunks on the
PBX if you use analogue terminals. I had a bad experience with ISDN2e
(BRI) ones once, although it appeared to be a clock sync issue - I'd
certainly be interested in hearing if you have better success.

I ended up having to use a large amount of such devices on an
installation not long ago where BT failed to deliver ISDN30 to a new
call centre building on time. We had to compliment them with some IVR
services as each SIM has its own phone number whereas the customer
needed to have up to eight calls all ringing into the same advertised
number. It worked a treat for several months until the ISDN was
installed properly.

I've implemented a few pbx/premicell installations for builing
companies.

The way around your issue above would be to have all 8 SIMs on the same
account - one that provides calls within group FOC.

Turn voicemail off on each SIM and then divert on busy SIM1 to SIM2,
SIM2 to SIM3, SIM3 to SIM4 etc.

Only SIM1 even need to be dialled.

Another thought, the company that I used toi worked for had need of
comms in an area where all the mobile phone networks had been completely
disrupted. I was told that they got some Manx Telecom SIM cards because
these would roam on to any UK network but calls either did not cost any
more or not much more than normal.
