BEVERLY, Mass., May 22 /PRNewswire/ -- Empirix invites you to join Chad Hart Wednesday, May 23rd at 11:00 AM EDT for a practical and informative discussion on Testing for Real World VoIP Problem Scenarios.

VoIP networks are subject to a number of known issues that are just beginning to become relevant as VoIP reaches the mainstream. Some of the most common issues include:

-- Mass calling events - when an atypically large number of users attempts to make calls within a specified time period, stressing the network beyond its planned utilization; -- Power outage restoration - a flood of registration messages occurs when power is restored after an outage; -- Peer network floods - peer networks can unintentionally overload other networks if interconnecting equipment is not configured properly; and -- Malicious attacks - hackers can mimic the above scenarios and cause a number of other nuisances and security breaches.

Surprisingly, many Tier 1 carriers have already found themselves unprepared for these scenarios and as a result, they have experienced major outages and service degradation.

Drawing off actual carrier experiences, this webinar will examines each of these VoIP issues in detail and provide guidelines on how to set up tests, simulate, and analyze each one in the lab so that they can be avoided in the field.
