AT&T Migrating Phone Network to IP

Posted by CowboyNeal on from the keeping-up-with-the-jones dept.

prostoalex writes "Following the lead of Sprint and Telus, who are moving their telephone networks to IP, AT&T will spend $3 billion to migrate to an IP-based network. By the end of 2005 about 270 legacy systems will be retired." The article also notes how the current ratio of packet traffic to voice is already 8:1.

    As this article states, the bandwidth required for VoIP can be huge. I would seriously hope to see some more advanced algorithms or better yet, more bandwidth installed, before these systems become more heavily adopted.

      Too bad your link refers to corporations using VoIP on their LAN/WAN as an alternative to traditional telephony. What we're talking about here is telephone operators using IP as a backbone transport (as opposed to voice over ATM VCs, etc). For telephone providers, VoIP has some excellent advantages, the most notable being consolidation of existing infrastructure (ie, being able to use the same lines for both voice and data).
