Closed Thinking




If one compares the culture of the telecommunications industry to that of the Internet,
it  is sometimes difficult to believe the two are related. The Internet  was designed by
enthusiasts,  whereas contributing to the  development of the PSTN is impossible for
any individual to contemplate. This is an exclusive club; membership is not open to
just anyone.*

The International Telecommunication Union (ITU) clearly exhibits this type of closed
thinking. If you want access to its knowledge, you have to be prepared to pay for it.
Membership  requires proof  of  your  qualifications, and  you will be  expected to pay
thousands of dollars to gain access to its library of publications.
Although the ITU is the United Nations’s sanctioned body responsible for international
telecommunications, many of the VoIP protocols (SIP, MGCP, RTP, STUN) come not
from the hallowed halls of the ITU, but rather from the IETF (which publishes all of
its  standards  free  to  all,  and  allows  anyone  to  submit  an  Internet  Draft  for
consideration).
Open protocols such as SIP may have a tactical advantage over ITU protocols, such as
H.323, due to the ease with  which  one  can obtain them. Although  H.323  is  widely
deployed by carriers as a VoIP protocol in the backbone, it is much more difficult to
find H.323-based endpoints; newer products are far more likely to support SIP.
The success of the IETF’s open approach has not gone unnoticed by the mighty ITU.
It has recently become possible to download up to three documents free of charge from
the ITU web site.†Openness is clearly on its minds. Recent statements by the ITU sug-
gest that there is a desire to achieve “Greater participation in ITU by civil society and
the academic world.” Mr. Houlin Zhao, the ITU’s Director of the Telecommunication
Standardization Bureau (TSB), believes that “ITU should take some steps to encourage
this.”‡

The roadmap to achieving this openness is unclear, but the ITU is beginning to realize
the inevitable.
