Newly published data from Infonetics Research indicates that worldwide TDM system revenue fell 15 percent between 2004 to 2005 while IP PBX revenue rose 23 percent.
The analyst firm’s latest Enterprise Telephony report said that combined global TDM and IP PBX systems revenue totaled $8.1 billion in 2005, a 12 percent increase over 2004.
The sector is expected to grow 43 percent between 2005 and 2009, when it will reach $11.6 billion as organizations continue to move to VoIP.
In that five-year span, Infonetics predicts that IP PBX revenue will jump 82 percent while TDM revenue will plunge 88 percent.
