Notice that in some areas it is now possible to become a carrier without doing SS7. The company I work for is in the last stages of transforming into a carrier, both for fixed and mobile. That is, we now actually own our own fixed and mobile Danish number ranges and we have our own SIM cards. We don't own any cell sites, but mobile calls are actually switched through our infrastructure, not just handled by the provider who owns the sites. This makes it possible to treat cell phones as if they were SIP phones. As an example, Asterisk is able to provide BLF showing the status of cell phones. Interconnections with other carriers will be SIP only, and all of this is done purely with Asterisk! We only (ok, with a few exceptions) sell hosted PBX solutions, so we aren't in general a price-competitive choice for pure termination/origination. /Benny PS: Sorry if this seems like an advertisement, but I do believe that what we are doing is a new and exciting direction for Asterisk. Like in my other posts, I have avoided mentioning the company I work for. _______________________________________________ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
