Asterisk Termination and ENUM

I discovered east interesting post of the completion of the saved asterisk as “unpublished” it dated 6-20-2005. I must have puestolo to a side to work in some other projects. I thought that now it would publish it since still it has some pertinent thoughts. Reading my article, it could not help but to notice to that he is two years later and still is no a network that watches with fixedness of VoIP of the important intra-company that I am found out (with an exception - VPF). Then I have been discussing in my thoughts to start off for of 2 years, waited for a class of model of P2P IP-PBX where a IP-PBX of communications of the company To with IP-PBX of company B initiating a call of exit in the tariffs of local calls of company b. The other panorama is that you could simply initiate a call of the company To a an extension in the company B that travels on the IP. In panorama you can bypass ITSPs entirely or the necessity of the entrances of VoIP. An option is for the company To “a watching directly with fixedness” with company B, making contact them with enemy with and forming some adjustments of the encaminamiento of the call. Nevertheless, the company To would have to make contact with enemy with a several companies to watch with fixedness with before making any saving of cost.

The other option as I mention down, you would require a certain class of of third person trusted acting whereas a mediator and centrally to organize to all the several pairs to reach the critical mass needed for the true savings of cost of the telephone. ENUM assumes to help with that, but the carriers are not undertaking exactly certainly to offer ENUM and “free” nonservices of ENUM. An interesting registry of ENUM is of the fabric that watches with fixedness of the voice (VPF). The ENUM registry is based on the standard of the IETF (RFC 3761) that the telephone numbers of the maps to Internet (URL) treat and use an architecture of the operations search based on the DNS that constructed their own registry of ENUM, which it is a service that watches with multilateral fixedness that allows that the organizations send and who they receive calls between members directly, the IP end-to-end, for no honorarium of the completion, including no cost to place numbers or to ask the registry. He is free. To let to me repeat that - he is FREE! To ask the ENUM registry is freely and so a call is finishing to another client of VPF. Thus, as the VPF adds more corporations to their list of the client, this also increases the call numeral FREE that you can do. Kudos to the VPF that is not hoping around public ENUM finally to remove. I exposed the advantages of ENUM in my “ENUM ENUM ENUM” the post, that is a good refreshment in ENUM and I it compares registries public of ENUM against deprived registries of ENUM.

The authorization, without more future adieu is the post here that I ignited 2 years ago. To enjoy…

The asterisk has had the capacity to call the other PBXs asterisk to finish calls on a connection of the IP by an absolutely certain hour. Thus, if you have multiple branches all with the PBXs asterisk, you can finish calls on the connection of the IP for free.

The Newby hunter raises in Telx and me he discussed how it would be very easy that the users of the PBX of the asterisk assemble in a massive community of the asterisk and “to share” your minutes of the connection and trueque/de the interchange. Let us call it “company that watches with fixedness”. It is really a form “of telephony of the company of the pair-to-pair” really. In theory, you can obtain a “cut” of the yield for the minutes of the PSTN that say aloud of your asterisk PBX. This is an easily frightened concept from all the companies can to “pair” with other companies and essentially another nightmare for the companies of the telephone denies possible the necessity of the PSTN altogether - caused by VoIP.

There are two panoramas when watching with fixedness between corporative IP-PBXs two. It is where the first panorama a IP-PBX of communications of the company To with IP-PBX of company B initiating a call of exit of the PSTN in the tariffs of local calls of company b. Company B loads the company To finishing the call. The second panorama is that you could simply initiate a call of the company To a an extension in the company B that travels on the IP. Since it is throughout IP, the call is free.

By all means, system of asterisk uses his protocol propietary of IAX for communication of Inter-Asterisk and SIP not standard, so unless IAX is supported by all the IP-PBXs (that is not going to happen), this “particular panorama doomsday” for the companies of the telephone can as soon as to be a dream. Also it requires that each confidence of asterisk IP-PBX the other IP-PBXs of the asterisk not to outside abuse or maximum towards his limited resources of exit of the PSTN.

Hardly imaginarte if the protocol of the mature SIP to the point where you can “surely watch with fixedness” with another SIP-based IP-PBXs and a certain class of clearing house takes care from minutes, the interchange of the yield, the etc. of exchange by all means, you could bypass a clearing house altogether and finishes of lets IP-PBXs outer of the SIP mark outside towards the excessive IP through your connection of the PSTN gratuitously, but it would have to be a certain level of the “confidence” to allow that this prevents abuse.

In theory, you could only load outer IP-PBXs after criteria have been solved certain of a use, but that one opens the door in the fraudulent practices of the invoicing. The company To could say that company B you must $500 to make calls of the SIP on its lines of the PSTN. That one is because a clearing house of third independent person would be necessary to prevent fraud with the invoicing. In theory, with quite great a clearing house “trusted” you can assemble this network of the clearing house and it would provide the minus encaminamiento of the cost and would calculate what yield you must that finishes invite your lines of the PSTN. Essentially, using your corporative IP-PBX beams your own small company of the telephone that makes your corporative IP-PBX a source of the yield instead of a responsibility.

In a way very similar to this idea, it appears that a called AsteriskOut company is using the multiple asterisk PBXs for the completion. It read the forums of VoIP carefully and I seemed east thread of spiral of the asterisk in the forums of VoIP where a company of leveraging is asterisk to finish the calls of VoIP, but does not appear they is constructing no class of model that watches with fixedness. AsteriskOut has some decent tariffs, including hardly $0,016 by the minute for the completion of the E.E.U.U.

Is to watch with fixedness of company-to-company IP-PBX as soon as a dream? With the aid of a great one and data base “it frees enough” of ENUM is certainly possible. Or perhaps with the continued growth of the asterisk, the opened community of the source will create a popular asterisk ENUM (AENUM) the registry his the own one that will reach the critical mass and even makes the other IP-PBXs assemble. Only the time will say.
