‎Yeah, poking around metro Atlanta, which is quite pooled, there do seem to be quite a few A block assignments floating around. -- Alex Balashov | Principal | Evariste Systems LLC 303 Perimeter Center North, Suite 300 Atlanta, GA 30346 United States Tel: +1-800-250-5920 (toll-free) / +1-678-954-0671 (direct) Web: http://www.evaristesys.com/, http://www.csrpswitch.com/ Sent from my BlackBerry.

If so, they'd still have LRNs, since LRN-guided routing is a requirement of pooling. So, who still has non-pooled 10K blocks? Is that common in metro, or largely a trait of rural LECs? -- Alex Balashov | Principal | Evariste Systems LLC 303 Perimeter Center North, Suite 300 Atlanta, GA 30346 United States Tel: +1-800-250-5920 (toll-free) / +1-678-954-0671 (direct) Web: http://www.evaristesys.com/, http://www.csrpswitch.com/ Sent from my BlackBerry.

So they need a totally accurate way to prevent a cell phone call from originating from their dialer.  The only thing I can think of is some sort of LRN dip + LRN-to-carrier-type response.  One of their people talked to Neustar, but didn't get great answers because he doesn't really understand telephony.  Before I get in touch with Neustar, I thought I'd see if people here have some ideas. If you provide a commercial product for this, please feel free to tell me so on or off list, the customer is willing to pay for the service and we're open to all options.  I don't have a budget number yet but manual dialing is going to cost them quite a bit for some types of studies. _______________________________________________ VoiceOps mailing list VoiceOps@voiceops.org https://puck.nether.net/mailman/listinfo/voiceops -- Kidd Filby 661.557.5640 (C) http://www.linkedin.com/in/kiddfilby _______________________________________________ VoiceOps mailing list VoiceOps@voiceops.org https://puck.nether.net/mailman/listinfo/voiceops _______________________________________________ VoiceOps mailing list VoiceOps@voiceops.org https://puck.nether.net/mailman/listinfo/voiceops
