VoIP - What is the Problem? (Page 2)

Date Posted: 2006-03-10

For most this is not an issue when they have high speed internet access, however, it can become a problem with satellite links or any other system where unusually long distances and many hops are involved.

On private networks, there is rarely a problem using VoIP and many companies with internal networks (such as telcos and power companies) use VoIP to communicate within their organizational network structure.

However, when the available end-to-end bandwidth is less than 256 Kbps, a good VoIP system will require mechanisms to overcome fragmentation of the data stream.

Security is an issue everywhere on the internet and what this means is that VoIP also needs to deal with firewalls and NATs (Network Address Translation). While some systems can do NAT and firewall traversal on their own, others require the use of SBCs (Session Border Controllers) to manage the traversal.

One major, though non-technical, challenge to VoIP, comes from traditional telephone service providers who are being by-passed by consumers who love the extremely low (or zero) long-distance charges they can get by using VoIP. Exactly how this works out over the long run will be fascinating to watch. In the meantime, VoIP services are continually being improved and extended. Enjoy them.
