Installing the Sonus products is part of the carrier\u2019s stated long-term migration from circuit switching to packet switching in its network.Having Verizon as a customer is good for Sonus. They\u2019re in a tough spot along with other\u00a0softswitch\u00a0vendors, selling next-generation telecom equipment at a time when telecom spending is pinched. Long-term, it would be great for Sonus or any softswitch vendor to have Verizon as a customer buying lots of equipment for a significant, sustained network migration. But that is still a ways off.To put it in perspective, Verizon announced earlier this month that it spent $6 million on traditional switch upgrades for switches that serve Boston\u00a0- more than the Sonus deal. In making the Boston announcement, Verizon noted that over the past three years, it has spent more than $2 billion just on the network that serves Massachusetts. So the Sonus purchases are a spit in the ocean.The flip side is that some day, Sonus and other softswitch vendors may be in a position to take a larger share of the ocean.For now, Verizon and other major U.S. carriers seem to be trying various softswitches as they have the need to expand switch capacity, and moreso with in long-distance networks than in local networks. Verizon has previously announced using softswitch gear from\u00a0Telica\u00a0and\u00a0Nortel, so it clearly is shopping around and putting many vendors through their paces.From Sonus\u2019 point of view, it now has some pretty big customers that represent a large chunk of its income. In addition to Verizon,\u00a0Qwests\u00a0and\u00a0Global Crossing\u00a0represent at least 10% of Sonus\u2019 revenue. Wall Street analysts seem to like this. Raymond James Associates, for example, took this information and boosted its projections of how much Sonus will sell this year from $78.4 milllion to $89.8 million. It boosted its 2005 revenue projection from $217.8 million to $225.7 million.This means two things. First, Raymond James thinks Sonus will do better than it previously thought. Second, it believes that Sonus will still be around in 2005. That\u2019s good for Sonus and it\u2019s also good for the industry that telecom network conversion is starting to happen.
