when free requires payment it’s not free.. duh?

Filed under: curiouserly, ITSP, SIP — Tags: — Seth Wisely @ 19:14

inum is free after you pay money in many cases. wow, what a not great deal!  Some FEW providers honor the American language and provide an inum at no cost.  Thanks: VoxAlot, FonSwitch, Callcentric

SIP Broker supported providers are far less hassle than inum in certain cases

I’ll be sure to post when I find a provider on the inum list that provides an inum and inbound use without a fee.. until then it’s a bait n switch scam

  • callcentric inum is free when you don’t live in the USA for e911 recovery fee *nod* *wink*. If you do live in the USA it will cost $5.  callcentric, however, does really offer free SIP URI calls. Callcentric provides its own set of PSTN gateway numbers for fee-calling [not free] or for calling other SIP/iNum callcentric clients.  There were too many characters needed in a dialstring for my phone but it is likely possible with the new $50/mo data penalty “smart” phones.
  • FonSwitch inum is free.  NO purchase required. Instantly added to account after selection from a dropdown.  FonSwitch offers free SIP URI calls
  • VoiceMeUp “free” inum offer is not free
  • BlasterPhone “free” inum costs $5 and requires gateway to “directly” call iNum. “inum available to paying customers only”
  • voxalot issues inum to all basic accounts: +883 5100 04 xxxxxx (where xxxxxx is your Voxalot number)

I don’t expect free service arbitrarily; I do however expect integrity.  Stand by your offer.

updated: corrections applied. Callcentric is free when you don’t “live” in the USA 😉 FonSwitch is always free inum no crazy e911 recovery fee AND they allow you to choose an iNum to your liking from a block of iNums.

Actually free iNum SIP providers

  • callcentric
    • free iNum
    • no SIP SIMPLE presence
      • must emulate presence with jabber [XMPP] (softphones)
    • free voicemail
    • server side filtering [limited]
    • web UA registration status
    • no SIP trace
  • fonswitch
    • free iNum
    • SIP SIMPLE presence
    • free voicemail
    • no server side filtering
    • web UA registration status
    • no SIP trace
  • voxalot basic
    • free iNum (provider iNum prefix + usernumber)
    • unknown SIP SIMPLE presence
    • unknown voicemail freeness
    • unknown server side filtering
    • web UA registration status
    • no SIP trace

I earnestly appreciate being corrected; I own- and apologize for my errors.  One gains nothing by willful ignorance.

presence: RFC 3856/5264? et al

I’m always on the look out for ways for friends’ families money to keep in touch (internationally) inexpensively.  For those who have free incoming mobile calls (UK/EU?)I would hope incoming SIP calls would be similarly free; iNum fits the bill nicely as the dialing party [ultimately] need not fuss with PSTN gateways or codes.  Rather than suggesting they invest in an excellent headset I suggest they opt for an ATA for “normal” phones.  ITSP and similar are kind enough to provide the free SIP calls, peering aside, it’s a “do a good turn daily” opportunity.  I have been recommending the SPA2102 with latest Cisco firmware for home users behind cheap ISP CPE (with joyously crippleware NAT) other suggestions will be warmly received.  Verizon FIOS westell gateways are the worst for ATA behind NAT with ‘SIP ALG’ that is nearly impossible to disable depending on firmware- and hardware versions.  It seems walled garden is not far enough; FIOS gateways seem hell bent on raping SIP.

future checks

  • SIP Presence subscriptions : SIP SUBSCRIBE/NOTIFY
  • SIP Presence publishing : SIP PUBLISH
  • SIP Presence document : SIP PIDF

  1. iNum with BlasterPhone is FREE! The US$ 5 required is for credits to make outbound VoIP calls.

    — Seth comments on comment —

    [Free requires that there be no payment. Should one wish to use BlasterPhone for free inbound minutes as BlasterPhone claims is possible BlasterPhone ought allow iNum account creation without REQUIRING payment information be provided as part of the process. BlasterPhone ought improve their understanding of the word “directly”, too. Calling a gateway, and entering an iNum is not “directly to your iNum” — Seth]

    • We do not sell iNums, we sell services, and they are not free! However, our customers receive free iNum when buying our service.

      As per the “direct” calls to your iNum – it is already a fact:

      —Seth comments on comment—-

      [You might want to remove your partner listing on the inum site offering “free” inum then hadn’t you? I take issue with your abuse of the American language. Perhaps offer “inum as a complementary feature for all paying customers”; that is similarly NOT free. Yes, I had read the inum PR. However your site directs patrons to call pstn gateway number and subsequently enter an inum. That is not a direct call.]

  2. Hello Seth, I’d suggest you read the information on our site regarding iNum. It would appear you may have been mistaken. iNum has always been free. We were amongst the first iNum providers when it came out, and completely support the project. Charging for iNum would go completely against its intent.

    The following is a link to our products page, which I’m sure you can find cached on various sites:

    When you register for an account at FonSWITCH, and order an iNum number, you get it right away. You can call other iNum customers with 0 charge, and you can receive iNum calls with no charge.

    It costs $5.95 a month to obtain a US DID number.

    Please have a look and let us know if you have any questions.

    I was either mistaken at the time of my test signup — if so I apologize to fonswitch — or the site layout has changed. One can indeed acquire a free inum from fonswitch — at no cost.

    Once one has created an account, confirmed email link, logged into fonswitch, click “my account” [top middle], click “iNUM” [between SIP settings and DIDs], pick a lovely iNum, click “get it”, and it’s instantly added to the account. Click “sip settings”, select the newly assigned free inum from the drop down for client configuration information. Be sure to change your password as it defaults to your phone number (inum or did).

    fonswitch supports sip presence unlike callcentric but lacks server side filtering anywhere near callcentric. fonswitch also appears not to peer with SipBroker so the only PSTN gateway is via iNum very tiny list. Both fonswitch and callcentric offer free voicemail. fonswitch iNum account addition is nowhere near as circuitous as callcentric and fonswitch does not attempt to squeeze an e911 recovery fee from USA citizens. Those wishing the best of both worlds will need either Callcentric+jabber or fonswitch+hostedPBX
