said Tuesday. Companies usually meet the requirements first in states mandating them, later moving to the rest, said Nick Maier, a senior vice president at RedSky Technologies. The FCC has left to states any E-911 requirements on intracompany networks, he said at VoiceCon in San Francisco. Virginia is the latest state to enact a law, Maier said. PBX and multiline telephone systems installed there after 2008 must provide automatic number and location information to the local public-service answering point, he said. Businesses anywhere can adopt IP telephony and unified communications confident that E-911 will work, Maier said, but Session Internet Protocol (SIP) communications presents challenges. It typically works peer- to-peer, with no call server in the middle and multiple users sharing a uniform resource identifier. But “location can be embedded with the call, which will streamline the 911 process,” Maier said. Technology still is being developed to enable a national routing system to translate between conventional phone numbers and “SIP-name-at-domain type designations,” Maier said. RedSky charges a company with 1,000 employees about $40,000 to license its E-911 software; one with 10,000 workers pays about $150,000, he said. Maintenance runs 18 percent of the license fee yearly, Maier said. Customers also must pay a telco about 7 cents monthly per user for record storage, he said. Alternatively, the capability is available as a service for about 50 cents an end point monthly, Maier said. He said coverage of nomadic users runs $1 a month each.
