Common Language Location Identifiers (CLLIs) are required by service providers to identify specific equipment for code routing functions in the public switched telephone network (PSTN) as well as wireless and VoIP networks.  CLLIs are required for LERG and Tariff 4 purposes as well as for ASR and E-911.  Should your company require new CLLIs due to equipment upgrades or simply require CLLIs to identify new equipment locations, JSI's Network Services group can assist you in ordering.  You can submit these requests to us via e-mail using this form; or, if you prefer, you can download this form and fax your request to us, at 240-556-1399.
