asterisk users - Feb 2005 - FRS / FRS/GMRS 2-way radios as SIP clients

Any one know of software that allows 2-way radios as VoIP(SIP) clients,
besides dingotel's usb & mic cable trick ?
http://www.dingotel.com/2way/requirements2way.asp

They might be ok if the SIP client was not hardcode to their own SIP proxy
Has anyone tried any hacks to get the 2-way radio SIP client to regsiter to
a * box.

hmm chan_frsgmfrs anyone? using the usb/mic cable under linux :)

Not sure where they hang out.... you might look here..
http://www.voip-info.org/tiki-index.php?page=Asterisk%20cmd%20Rpt
and here..
http://zapatatelephony.org/app_rpt.html

should be some contacts on these pages to get you started.

What exactly are you trying to achieve?

On my repeater system, I use the RC210 repeater controller with the 
Phone Patch option. This is then connected to my Cisco ATA and then onto *.

Users can initiate phone calls and callers can either command the 
controller or initiate calls to the radio operators (although I have 
this bit disabled for legal reasons).

There are many Phone patch type devices that could be paired with a 
radio (MURS/FRS/GMRS/HAM/etc) which in turn would require connection to 
an ATA.

As for "where do they hang out". On the radio of course! With masses
of
specturm available to even the most modest licencee why would we join a 
IRC channel?

You can find me on 53.81MHZ, minus shift, 136.5HZ PL

OK this is what I want to to do
I want to use these inexpensive FRS/GMRS  2 way radios
like Motorola Talkbout line series
http://commerce.motorola.com/cgi-bin/ncommerce3/CategoryDisplay?cgrfnbr=9&cg
menbr=126
or
uniden http://uniden.com/product.cfm?product=GMR1088-2CK
as extensions on my asterisk pbx

I do not realy want staff to make out going calls,
(would be nice, but i dont see any with dtmf keypads)
but I want to stay in touch with them and let them get voice mails, and
take inbound calls from the pbx...
when they are a distance from the office think tourist recreational area..:)

the sn-920 do give the range but the price point & industrial casing is
lacking

TC,

Just a word of caution.... You might want to check with your equivilent of
the US FCC on regulations regarding using FRS gear in a commercial
application. Here in the US thats a no-no (although it is widely
disregarded). GMRS in the US requires an inexpensive license but does
support commercial application.

Aside from FRS, interesting thing about this, is that they are very careful
to treat the VoIP part under the same rules as FCC HAM i.e. if I were in
Canada and I was using, say, Asterisk or VoIP in general to hook into this
thing with it's transmitter in the US, technically, I wouldn't be
allowed to
talk on that freq. because I wasn't licensed to use that freq in the US,
even though the transmitter/owner is licensed correctly in the US!

Seems odd, because I believe the rules were established at least in part to
avoid crosstalk issues etc. But it seems VoIP changes the rules a bit here.
What if I was a licensed HAM and I was in Canada and using VoIP to talk to
my transmitter in the US? Is that ok? I can think of all kinds of wierd
scenarios. 

I know of the rule that prevents you from interfacing PSTN to HAM, but what
about VoIP? Unregulated. As far as the FCC is concerned, my Asterisk box is
the same as a Linksys hub.

To the hams on the list: How can something like this be policed? Is there a
ruling, or precedent on this? My 10 second google didn't turn up anything
close.

>Pure guess... in the US, probably treated like rtty?
Interesting thought. There's no 'r' part in the 'tty' part
in this case,
though (unless you were transmitting rtty through VoIP).

This whole thread opens up all sorts of interesting ideas. Chris A's musings
are interesting as hell too. My wife's gonna be mad at me tonight because
I'm going to be staring off into space again...

I checked a couple of the software voip interfaces (echolink, irlp) but none
of the radios
these projects hardware talks to looked like they supports fsr/gmfrs
repeaters.
could you post a link or 2 that has a hardware interface to frs/gmfrs
repeater
the would talk to these motorola or uniden consumer 2-ways radios ...
using what you call a "phone patch" type devices

in art ..

* Box --->ata (prolly sipura 200) ---->

these 2 above 2 items some urls :)
uniden/moto 2 way radios
