  1. Add your module to /etc/modules


    # /etc/modules: kernel modules to load at boot time.
    #
    # This file contains the names of kernel modules
    # that should be loaded at boot time, one per line.
    # Lines beginning with "#" are ignored.
    saa7134

  2. Add options saa7134 card=42 to the end of /etc/modprobe.d/options

    # Enable double-buffering so gstreamer et. al. work
    options quickcam compatible=2

    # Default hostap to managed mode
    options hostap_pci iw_mode=2
    options hostap_cs iw_mode=2

    # Stop auto-association.
    # LP: #264104
    options ipw2200 associate=0

    # XXX: Ignore HPA by default. Needs to be revisted in jaunty
    options libata ignore_hpa=1

    options saa7134 card=42

Now reboot and you should be all set.

    The instructions for this project are incomplete, but you basically step on the circuit on each tile with a conductive sole shoe (you could use aluminum tape glued under your shoe) to close the circuits. I hope to be able to add more detailed instructions and pictures soon. For now, you can check out http://royconejo.host.sk/, it was heavily inspired from it.

    WARNING: Before anybody attempts to build this dance pad, please note that after a while I suddenly started having intermittent problems (it stops working). If I unplug it and plug it back, it starts working fine again for a while. I think the problem is caused by the wires connected to the circuit board being too long. It might change the inductance and/or capacitance too much and the circuit board can’t handle it. I don’t know much about electronics so If anyone know how to fix this, please let me know. I tried with a USB circuit board and a USB board with a PS/2 adapter without any luck.

    Getting DID numbers to ring Your Current SIP/VoIP provider

    1. Some DID Providers (including the ones above) offer forwarding to your current SIP URI, YourVoipUsername@YourProviderProxy

    OR

    2. MySipSwitch.com
    Go to SIP Switch : Use multiple VoIP providers with one SIP phone, and create an account. Ignore the dialing plans, but go to the bottom of the Config Page when logged in. Fill out the provider info, and under ‘contact’ put where you want it to ring YourVoipUsername@YourProviderProxy

    3. VoXalot.com(Voxalot - Home) (Cost: Starting at $15/year)
    -You need to perform a SIP Registration
    -If you want the number to ring somewhere else (not VoXalot) use their forwarding features.

    4. PBXes.com
    -Although slightly complicated, it can achieve forwarding as well

    Receiving Calls via VoIP on your regular PSTN Phone: People from around the world call a number local to them, then enter an extension when prompted which in turn rings your CellPhone or HomePhone.

    There are now 4 options, all of which achieve similar results, but at different costs and qualities:

    1. Receive Calls from Around the World through a local number: VoXalot, MySipSwitch,PhoneGnome (Cost: Free)
    2. Receive Calls from Around the World through a local number: VoXalot, PBXes, TPad, MySipSwitch, PhoneGnome (Cost: Free)
    3. Receive Calls from Around the World through a local number: VoXalot & PhoneGnome (Cost: $15 after July 16th)

    4.Receive Calls from Around the World through a local number: PhoneGnome and GTalk2Voip (Cost: Free)
    5.Receive Calls from Around the World through a local number: PhoneGnome, VoXalot, PBXes.com (Cost: Free)

    Commentary:

    There is two things two consider with each setup (in my opinion), reliability and voice quality.
    This remains my opinion, but the paid VoXalot option (3) produces best results with both, unfortunately it is no longer free. The next best one is the current number (1), quality is rather good, and it is free.

    Making VoIP Calls from your regular PSTN Phone

    1. To call any Voip User for which you have a Network Number (eg. a Gizmo/FWD/VoXalot/CallCentric number etc..):

    -When prompted enter *SipCode (find here SIPBroker - Provider White Pages) followed by the network number. eg.*747-1747xxxxxxx

    2. To Call an ENum number or a Toll-Free number (a Toll Free number not reachable from your location normally)
    -Dial SipBroker Access Number local to you
    -When prompted enter the full number in Country Code-Number format for an ENum call (you can also use *013-Country Code-Number)
    -For North American Toll-Free Numbers simply call in *1-800-xxx-xxxx format
    -All other Toll Free Numbers, including NA Toll Free numbers can also be called in CountryCode-Number format

Personally I would suggest paying with PayPal, and funding the PayPal payment with a credit card (giving yourself at least two dispute resolution possibilities, PayPal and your CC company, while avoiding having your credit card charged continuously)

    Voip Networks/Free Hosted PBX Systems

    1.VoXaLot: (Voxalot - Home)

    VoXalot can be best described as a service aggregator. In a few words they let you put multiple services together, to create a custom VSP. They are not just a PBX, but rather a network on their own…

    Free VoXBasic Service includes:

    • Incoming calls from SipBroker Access Numbers
    • Incoming calls via SIP URI
    • Incoming calls from DIDs forwarded to a SIP URI
    • Multiple Outgoing Providers can be registered (this supports most providers, except those that require SIP registration for placing calls)
    • Dial Plans or Smart Calling which lets you use the cheapest provider for each destination
    • Speed Dial List
    • Voice Mail (which can also be accessed from regular phones)
    • Automatic ENum lookup
    • Automatic Geo lookup for premiumnumbers in the UKand Australia (via e164.org)
    • Virtual Toll Free (A small script to let people call you from the Web: VoXalot can call their phones, at your expense, or their SIP URI and connect them to you)
    • Import/Export feature for Providers/DialPlans/Speed Dials to move them form one acct to the next
    • Can be used with any SoftPhone, ATA, and a number of VoIP enabled mobiles

    VoXPremium adds the following extra features:

    • Call Forwarding based on Caller ID or Provider and Time of Day(send incoming calls to SIP URIs or Phone numbers, so you can always receive your calls)
    • Web CallBack (enter two numbers and the providers to use for each number and place a call, hence using VoXalot form PSTN phones as well)
    • VoiceMail on the Web
    • Incoming Calls from third party providers via SIP Registration (VoXLite: 1, VoXPro: 5, VoXExtreme: 10)

    They also provide the SIPBroker service with 200+ donated access numbers around the world to call Voxalot and over 2000+ other SIP based VoIP Networks (millions of VoIP users) for free…

    They are associated with (but do not run) the only ENum service open to the end-user, e164.org

    2.PBXes(www.pbxes.com)

    They provide a hosted Asterisk based PBX service. Their interface remains faithful to the Asterisk interface in general, although it is much more user friendly. Their services include:

    PBXes Free: The Free account notable limits are a 10 GB usage, and 2 simultaneous calls, with a 60 min cutoff, and the unability to post in the support forums.
    PBXes Premium: Includes a full on PBX including among others Fax as EMail,a full AutoAttendant and Que system, and CallBack access to your Trunks
    PBXes Pro: Is geared towards businesses, providing a hosted PBX which can be customized for various clients, including much of the same features as the Premium acct.

    For a breakdown and description see: https://www4.pbxes.com/iptel_details_e.html

    3.MySipSwitch (SIP Switch : Use multiple VoIP providers with one SIP phone)

    MySipSwitch is a PBX service concerned solely with Call Routing. In avoiding the hadling of the actual audio stream their application runs much lighter. It is currently an R&D base being run by two technicians and sponsored by BlueFace.ie It provides the following fetaures:

    • Multiple outgoing SIP Providers
    • Outgoing Dial Plans
    • Multiple Incoming SIP Providers
    • SIP Registration unto a third party destination URI
    • A Call Routing facility handled via DIAL PLANS that has lately added support for multiple simultaneous call forwarding

    Their service is new, and the interface is a bit raw, but their outlook looks promising, and used in conjuction with other PBX services, can contribute to a solid VoIP arrangement…

    For more info see: MySIPSwitch Community Forums :: View topic - How to Use MySipSwitch

    4. LiberaILVoip (Partiamo con Libera il VoIP)

    Their website is in italian. They provide the following services:

    • Incoming and Outgoing Provider Registration
    • Dialing Rules
    • Incoming Call Filters and Call Forwarding
    • VoiceMail
    • Gateway Access (CallThrough)
    • Call Back access to your provider rates (the only PBX service to offer this for free to my knowledge)

    *Some limitations apply, will update when I have a better understanding of what they are

    5. GTalk2Voip (Voice-over-IP gateway for Google Talk, MSN and Yahoo Users)
    -Used in conjuction with MSN, Yahoo, GoogleTalk messengers
    -You create an account by simply entering your email in the home page
    -service@gtalk2voip.com (or something similar) adds you as a friend.
    -Open a Convo and type: MYPAGE
    -Click on the link for your account page
    -To CALL type commands on convo with service@gtalk2voip.com :
    SIP URI:

    Code:
    CALL user@provider.com

    MSN:
    If email is username@hotmail.com
    then type

    Code:
    CALL username_at_hotmail.com@msn.gtalk2voip.com

    If email is username@msn.com
    then type

    Code:
    CALL username_at_msn.com@msn.gtalk2voip.com

    GoogleTalk:
    If email is username@gmail.com
    then type:

    Code:
    CALL username_at_gmail.com@gtalk.gtalk2voip.com

    If email is username@DomainWithGoogleApps.com
    then type:

    Code:
    CALL username_at_DomainWithGoogleApps.com@gtalk.gtalk2voip.com

    Yahoo
    If email username@yahoo.com
    then type:

    Code:
    CALL username_at_yahoo.com@yahoo.gtalk2voip.com

    PSTN
    Type:

    Code:
    CALL 14161112323

    (always type number in international format)
    PSTN calls are not free, but you can now add your own providers to GTalk2Voip, and the call will be routed through them. Otherwise GTalk2Voip routes through its own providers and requires you have a balance
    -When calling someone for the first time using the commands above, chances are it will not go through, but they will receive a notice that service@gtalk2voip.com has added them as a friend, if they accept, the second time you try they will receive a call from service@gtalk2voip.com
    -This works much smoother in GoogleTalk, rather than MSN (have not tested with Yahoo)
    -They assign you a number *018xxxxx, that can be reached by dialing SipBroker Access Number + *018xxxxx
    or *018xxxxx@sipbroker.com (SIP URI calling), in all this cases you’ll receive a call on your MSN/Yahoo/GTalk messenger
    -You can also get a DID number, forward it to *018xxxxx@sipbroker.com, and your MSN/GTALK/YAHOO messenger will ring when someone calls you
    -There is a generic Voicemail if you don’t pick up, or you can forward to a SIP URI and receive calls to your current provider
    -You can use them to IM people not using same messenger (Voice-over-IP gateway for Google Talk, MSN and Yahoo Users)
    -You can create your own WebCall button (it calls you via Voip, plus uses one of your providers to call the other party and connect you together, if someone enter an actual number though, you will end up paying for the call, but at VoIP rates) (Voice-over-IP gateway for Google Talk, MSN and Yahoo Users)
    -In Summary, neat to play around with. It is a raw framework for now, not very user friendly, but looks promising.

    VoIP Networks/Other

    FWD: Free World Dialup (FWD | Home)
    -Free Calling between Members on their Network
    -Can be used with their SoftPhone/Other SoftPhones/ VoIP adapter
    -IM other FWD members, SIP-Users, AIM/MSN/Yahoo/GTalk/Skype/ICQ (FWD | Help)
    -Call other Voip Users on other networks
    -Receive Calls from PSTN using access numbers (only 2 numbers really)
    -VoiceMail
    -They plan to be offering paid FWDout/FWDin service soon
    -From personal testing the FWD Communicator, and adding IM contacts from other networks is glitchy.

    Gizmo Project/ SipPhone (Gizmo – A free phone for your computer / SIPphone - Call worldwide over your Internet connection with any phone)
    -Use with their SoftPhone/Others/Voip Adapter
    -More aimed at putting together IM and Voip
    -Free Calls to other members
    -You are assigned a 1-745 number (only valid within Gizmo, not from outside)
    -Can get a free 775 area code PSTN nummber (but requires a credit card and US adress)
    -Gizmo All Calls Free plan (Gizmo – A free phone for your computer - Help)
    If you have a friend that you regularly call or chat on Gizmo, once in a while when he/she is not on you can call their cell/home number for free. Both of you have to have Active status for All Calls Free
    -Claims to let you message and call MSN/GoogleTalk/Yahoo/AIM/Jabber/SIP users (this works some times and not others; from my experimenting MSN is the most problematic)
    -Is offering paid Outgoing Minutes/Incoming Numbers

    TPad (Tpad - The Global Phone Network)
    -Free calls to other TPad users
    -Use SoftPhone/Voip Adapter
    -Gotta pay for outgoing calls to real numbers
    -Can receive calls from other Users, or by someone dialing Access Numbers + TPad number
    -Includes Voicemail Service
    -The biggest plus is their access numbers in countries where it is commonly hard to find one.
    -Mentioned in the WorkAround above for local calls to your Cell/Home from around the world
