Shapefile\KMZ of Ratecenters
by voiceops＠ics-il.net July 6, 2021

July 6, 2021

Is there a source of shapefile\kmz data of ratecenters so that I can paint a better view of coverages? It's hard to tell where coverage is and isn't with just a spreadsheet. None of the networks I talk to ever have a realistic map of their coverage. ----- Mike Hammett Intelligent Computing Solutions http://www.ics-il.com Midwest Internet Exchange http://www.midwest-ix.com

8YY Traffic

Is there any reason I can't throw all 8YY traffic at my IXC tandem? In looking in my Metaswitch config, it appears that only 8YY traffic destined for my LATA (which doesn't really make any sense) goes to the tandem. Everything else goes out to a domestic termination provider. ----- Mike Hammett Intelligent Computing Solutions http://www.ics-il.com Midwest Internet Exchange http://www.midwest-ix.com

Market Leaders?

Last time I looked into this was Level3 and Global Crossing but that was some time ago. I know bandwidth has a close relationship with Microsoft for Teams because they say there are the only provider that can offer E911 services for Direct Routing for Teams. I find this odd because I thought all that was needed for E911 services was a connection to the PSAP or am a wrong?

Bandwidth is who provides MS?s calling plans for Business Voice (Teams calling). Wouldn?t surprise me at all if MS is their biggest customer.

Does anyone other than ShareTracker have data on market share? I saw this page when looking for something else. https://sharetracker.com/bandwidth-inteliquent-level3-and-peerless-tops-amo…<https://urldefense.proofpoint.com/v2/url?u=https-3A__sharetracker.com_bandw…> It didn't seem right that Bandwidth had more of the market than Inteliquent and Level 3 (and potentially Vonage and Twilio) combined. That lead me to doubt everything else in the report. ----- Mike Hammett Intelligent Computing Solutions http://www.ics-il.com<https://urldefense.proofpoint.com/v2/url?u=http-3A__www.ics-2Dil.com&d=DwQF…> Midwest Internet Exchange http://www.midwest-ix.com<https://urldefense.proofpoint.com/v2/url?u=http-3A__www.midwest-2Dix.com&d=…>

question about stir/shaken - iat and DATE header
by myaklin＠firstlight.net July 2, 2021

July 2, 2021

All, Pretty simple question here. When you do a verify request are you filling in the iat with your sbc's current date/time or using the DATE information from the invite? With Neustar the iat is currently optional. IQNT is basically removing the DATE header in a test we are doing by sending them a call and getting it back in a different region. It really does not make sense to me to use the DATE header because it could be messed with by anyone in the path. It is untrusted. The iat is trusted so when you verify it makes more sense to use the current date/time of your SBC because the limitation is 60 seconds from AS to VS. I imagine Neustar made it optional because their own system has some intelligence when it comes to this expiration of the AS. On top of that Metaswitch is not prepared for this situation. They are basically counting on that DATE header to be there in their recommended perimeta SBC config. They plan to fix it by using the current date/time. Just looking for how others are handling this. Just leaving it blank for now? Matt

TMobile Sending Calls to LRN not Called Number
by msutton＠avidphone.com July 1, 2021

Anyone else seeing calls from TMobile coming in with the LRN as the called number? The ISUP doesn't show the actual called number so we can't route the calls. -Matthew
