<H3>Skype must marry SIP</H3>
<P>Mahy thinks that eventually Skype will have to be connected to SIP, otherwise
Skype users will be let unable to talk to the rest of the world.</P>
<P>"Sure, he 'could' use something else, but that would be economic suicide.
When asked how he would get PSTN numbers assigned he said he would use partners
who are telecom operators to provide these. These providers are already using
SIP or H.323 and have no economic incentive to 'each' build a native-Skype
interface on the thin margins that Skype is hoping to garner from its
customers."</P>
<P>So, Faultline asked why doesn't Mahy write a connection to Skype, using the
APIs that Skype is intending to publish: after all, he has 13 million users? "He
doesn't have 13 million 'active' users, far from it, so it is really not worth
my time. I would rather spend my energy writing a free client with more
functionality that is fully open." So does Skype need to talk to SIP clients one
day or can it just talk to the PSTN and then route back out to SIP clients?</P>
<P>"That's missing the point, don't you think? Say a Skype user in India wants
to communicate with me in California on a SIP network. He can make a basic call
through 2 gateways with international toll charges.</P>
<P>"Its unlikely that I will see his correct caller ID, and dead certain that we
can't exchange IM, video, presence status, or do file transfers. A pair of
implementations using SIP could do this for free over the public Internet."</P>
<P>Talk then turned to the security that Zennstrom says exists in Skype that
doesn't exist in SIP. Mahy thinks the Skype approach is inviting viruses,
Zennstrom says this is not possible. According to Zennstrom there is little
danger of a call through Skype resulting in a route for a virus because the
recipient is told there is a call for him and is asked to call out to meet
it.</P>
<P>Mahy tells us that there are rapidly appearing firewalls that are
deliberately eliminating use of peer-to-peer networks, including the one Skype
sits on, because of security issues.</P>
<P>"Once my machine is infected with a virus, that virus can do lots of rude
things with the Skype API. The virus could call a PSTN toll or international
service from my account and leave it up for days. The virus could spam call my
entire buddy list a few times an hour. The virus could turn my computer into a
remote-control microphone. These are the kinds of issues that IT administrators
are concerned about. Also, many administrators want to block p2p to prevent
liability from the RIAA and similar groups. With at least one product the side
effect is no Skype."</P>

Dicas para instalacao de pbx residencial<BR></FONT><BR></DIV>
<DIV></DIV>O hardware parece servir a todos os serviços que vc quer, canais
analógicos - com zap, fax - não sei como fazer mas já li algumas coisas dizendo
como é possível, URA - fácil fácil com asterisk, e secretária - implementada com
voicemail.<BR><BR>Agora tenho uma dúvida, vc quer implementar a integração do
asterisk com o Skype? como se faz isso uma vez que o codec dele é proprietário e
os padrões fechados, já existe algum módulo do asterisk ou alguém que
desenvolveu uma solução que trata isso? Ou vc apenas usaria também a máquina do
asterisk como um gateway de internet? <BR>Pelo que entendi, vc quer usar o skype
para o pessoal da empresa se comunicar internamente, é isso?<BR><BR>
