According to research and consultancy firm Dittberner, over 16 million media gateway, softswitch and integrated VoIP ports were shipped during the second quarter. The 16.5 percent increase over Q1 due to ongoing carrier upgrade activity especially in CALA and EMEA, is further supported by reduced pricing stimulated by marketplace competition. Nortel Networks leads the market, having shipped 3.288 million VoIP ports. Siemens edged out Huawei Technologies into second place this quarter gaining 18.17 percent of global market share compared to Huawei’s 16.19 percent. CALA, EMEA and NA regions experienced strong growth – 43.94 percent, 31.17 percent and 25.6 percent respectively over the last quarter - while APAC saw a decrease of 9.8 percent over the last quarter. Dittberner expects to see further growth in VoIP equipment shipments over the next quarters as the migration to packet telephony picks up pace around the globe.
