Karen Hoffman, JSI's Network Services manager, can claim more than a dozen years' working behind-the scenes on numbering issues as a member of the Common Interest Group of Routing and Rating (CIGRR) Committee.  The CIGRR Committee meets four times yearly to review and discuss issues affecting the Local Exchange Routing Guide (LERG) or LERG database (BIRRDS).  The committee is comprised of representatives from all segments of the telecom industry; i.e., large and small incumbent LECs, CLECs, wireless carriers, and the consulting community.  A member since 1997, Karen has been instrumental in representing JSI client interests during mandated changes in the industry, such as thousands-block pooling and local number portability.

Karen is also a member of the Local Number Portability Administration Working Group (LNPA-WG).  Karen regularly attends the monthly LNPA-WG conference calls in support of the porting services JSI provides clients.  Given the recent FCC rule changes affecting simple ports and one-business-day porting, Karen's participation ensures that the interests of JSI clients and other independent providers are well represented.  Karen's pro-active stance also ensures that, as a company, JSI remains abreast of all developments and changes in porting procedures.
