Direct SIP Addressing? Not so Fast! |

From the November 14th, 2006 issue of Fierce VoIP:
It's the unglamorous stuff that usually makes the real difference between success and failure. One analysis of VoIP wonders when we'll be able to call a SIP phone by entering its SIP address instead of a conventional phone number. The answer: not any time soon. Addressing schemes are tricky things. Whippersnappers (and when's the last time you ever snapped a whipper?) don't remember how big a deal it was when email addresses went from specifying every step (ihntp!rutgers!abasin!dan) to putting all that routing information into the cloud (dan@fiercevoip.com). No one, mercifully, remembers x.400 email routing schemes, and the days of operator-assisted intercity calling are receding out of memory and into folklore. So when will we see SIP-addressed phones? Maybe never because someone will figure out how to move SIP addressing to an easier scheme--one, of course, that still doesn't require the PSTN for termination.
For more information about SIP addressing read this article from VoIPLoop: http://www.voiploop.com/index.php?option=com_content&task=view&id=1598&Itemid=34Private Reply to Ira Stoller (new win) |
