Call cabins with VoIP

[Diego Garcia]

Hi,

My name is Diego and i'm from Mexico City. I want some advice about
the best solution for Call Cabins with VoIP, cause i want to install
some cabins in several places in south of Mexico and Guatemala. I'll
use Satellital Internet in few cases cause there are in remote places
inside the jungle. But first i want to talk about which can be the
best solution for this.

I was thinking in voip phones connected to a router and all to a SIP
server, maybe with gizmo.com

Another solution is one PC with 4 USB ports connected to a USB phones
running 4 different VoIP clients like Gizmo or Skype (Maybe i need to
know better providers, if u can recommend me one I'm gonna thank a
lot).

Or another idea is about a Linksys PAP and some PSTN phones.

I hope anyone can help me decide what is the better solution for this.
Thanks in advance for reading this.

Best regards,
Diego García Mendoza

Where do most of your clientel come from?  If they come from the US you might want to consider setting up one of the lines with Vonage (US-based VoIP service).  For only $20/month you could get a US phone number so that the people staying at the cabin could receive calls without international tariffs.  Additionally, you get around 500 minutes for the $20.  I in no way work for Vonage, but am simply a satisfied customer.  Your setup sounds like it should really saise the appeal of the cabins.  Good luck!

Hi Diego,

I find it surprising that you are able to use satellite-based Internet
with VoIP. Are you sure that they will allow it?

Here in the states, I have a few very remote business customers that
cannot get Internet access except over dial-up, and then only at lower
data rates. (I have one who is so remote, they can only get a
fractional-T1 for WAN service!) We looked into satellite-based Internet
via three or four different carriers and they all had many restrictions,
including:
   -- Maximum per-minute total data capacity, after which progressive
rate limiting was enforced until no traffic for a specified time period
(20 minutes, if I remember correctly).
   -- Maximum per-hour total data capacity, after which throughput was
progressively rate limited for a 24-hour period.
   -- Maximum total data capacity per-24-hours (a few 10s of MB), after
which you were disconnected for 24-hours.
   -- No VPNs, no tunnels (GRE), no p2p, no VoIP, etc. One of the
services even said that all that was allowed was: HTTP(S), POP(S),
IMAP(S), and SMTP(S). (I even have a client in a major metro area whose
cable Internet provider has the same restrictions.)

Thus, my question: Are you sure your service provider will allow you to
do what you want to do and will they provide the required channel
capacity? If so, you are a lot luckier than we are here in the states!

Hi Diego,

Are you planning to connect to the Internet via Prodigy Infinitum? If so,
you should be aware that Telmex does its best effort to block SIP. You may
want to consider using IAX.

Thanks for all the answers

About the satellite restrictions i have to check but that could be the
Guatemala provider and they provide voip service or at least that says
their web. But it's true i have to know that. Thanks for the info Jon.

Junaid, here aren't unlimited services on GRPS but now there are some
unlimited packages on 3G so there can be an option. I've a friend who
own one of this and i'll use his service for some tests. Thanks for
the idea.

And Sergio, yeah i'll use infinitum on some places in Mexico, thanks
for the warning about the SIP and Telmex, i didn't knew it :/ Damn
monopoly.

Thanks for all the info. And what you think about the procedure? Which
equip should i use? or maybe the pc solution with software clients and
usb hardware sounds good? I guess the skype and the gizmo prices are
nice.

Really thanks for all your advices.

Hi Jon

I think the 'restrictions' on VoIP and VPN are because they don't work on most (HughesNet, WildBlue, for instance)
satellite platforms due to the very high latency.
There are a few,( http://www.skycasters.com/broadband-satellite-vpn/index.html ) who have designed around the latency
problem, but they're not cheap either.<s>

Good day,

I would suggest running you own SIP server by making an asterix server and getting a diguim card if you wish to connect to analog or digital lines

Diego,

I recommend you connect normal, non-IP phones to a VoIP gateway such as
Quintum or Audiocodes. Then you connect the gateway to the ADSL. If your
plan is to only give telephone services, I wouldn't recommend using a PC,
they are harder to maintain and your clients/employees can mess with them.
Don't use IP phones either; they too need maintenance, and in such a large
and dispersed deployment they can be a real pain.
What kind of PBX will you use to route the calls? Are you planning to do
load balancing?

Regards,

Sergio

Hola Diego,

If the cabins are within wifi reach of each other, you might look into
doing a mesh network with Linksys WRT-54G routers running Sveasoft in
WDS mode.  Then you can place a router in each cabin with a VoIP phone
or an ATA adapter and regular phone.  Off the main router you have a
PC as a firewall/sqid server/etc. connected to your internet
connection.  Also running on this PC is a VoIP server like Asterisk
running SIP and/or IAX, and possibly even able to connect with Skype
using the ChanSkype driver.

Depending on configuration, you might need only one SIP account with a
provider (or even just Skype), and thus one dial-in number, and via
Asterisk you can assign extensions to each cabin for dial-in number,
voicemail, etc.

Also, the WDS mesh network would provide wifi coverage permitting your
guests to use their laptops to surf, as well as letting them use their
VoIP softphone/Skype/etc. of choice from their laptops, or a PC you
have in the cabins for their use.

I hope this helps, and please send me (off-list) some details of where
your cabins are located, etc.  Some gringos may need to jump fences
too someday ;-)

Cheers,
