Tandem Dropping Calls
by voiceops＠ics-il.net Oct. 4, 2022

Oct. 4, 2022

We have a new customer that has an increasing number of TNs they can't call. I've traced them all down to going through our local Frontier tandem. Calls from other phone numbers on our network are fine. Two of the numbers are with Frontier, just another ratecenter off of that tandem. The third we know of goes to VZW. I submit a ticket to Frontier with source number, destination number, and call date\time for the last set of problem calls, all within the previous 24 hours, out of our Metaswitch SAS. Frontier replies: Per Software Engineering/DBA: Did not find mention call in IRIS (SS7), did find at that time a call to 815-824-XXXX, not 815-824-YYYY. SS7 show that call at 14:51 came in on DNC tgn 1011, GN089085, OPC=005-092-136 and terminate to DeKalb switch. Verified incoming call in switch, switch not blocking terminating to line. **31 - Normal. Unspecified. This cause is used to report a normal event only when no other cause in the normal class applies**. Found no trouble in switch translations/routing. Status: Cleared Awaiting Cust Verification So we have a very different definition of "cleared". I call a problem cleared when it's resolved, not when the reason can't be found. So Frontier: 1. Can't find one of the three calls I sent them. 2. Doesn't chase the problem to the end of the line. 3. Clarifies that the ISUP error I'm getting means they don't have a reason for it to be closed, so probably not a normal circumstance. 4. Doesn't investigate why there's an unclassified release. How can I incentivize Frontier to actually figure this out? ----- Mike Hammett Intelligent Computing Solutions http://www.ics-il.com Midwest Internet Exchange http://www.midwest-ix.com

Number -> Tandem Lookup
by voiceops＠ics-il.net Sept. 29, 2022

Sept. 29, 2022

Say I have a phone number (or an LRN). How do I find out what tandem switch it's actually homed to? I know that the phone number (or LRN) should be homed to whatever tandem switch the ILEC in that rate center is homed to, but A) that doesn't always happen and B) you can't always easily (telcodata.us) determine what tandem the ILEC is using. I know I can look SHAs up in the LERG, but I don't have that access. Is that the only way? ----- Mike Hammett Intelligent Computing Solutions http://www.ics-il.com Midwest Internet Exchange http://www.midwest-ix.com

Any higher-ed contacts? for EDUCAUSE talk
by lindsey＠e-c-group.com Sept. 20, 2022

Sept. 20, 2022

Is anyone on here with good connections with Higher Education (Colleges, Universities, Professional Schools)? I'm doing a presentation at EDUCAUSE, the Higher-Ed IT Conference, on the changing uses of Voice communications in that space. I'd love to chat briefly to see how folks are using the phone system at High-Ed institutions and how they see that changing. -- Are campus users using the phone systems differently now than they did a few years ago? -- Does every new staff or faculty member want a phone number? -- Who are the heaviest users of the voice system? -- Have you recently removed any parts of the phone system? (E.g., Dorm room phones, blue-light emergency phones, desk phones for staff in favor of MS Teams, etc.) I'd appreciate any pointers.

What attestation for verified calls?
by ciscoplumber＠gmail.com Sept. 19, 2022

Sept. 19, 2022

Has the industry as a whole more or less settled on a particular attestation level when marking a call as verified in the CNAM? If my phone receives a call and it says verified does that mean the call was at attestation 'A' only, or 'A' and 'B', any level of passing attestation, etc.? Thanks

NANPfund.com?
by compuwizz＠gmail.com Sept. 12, 2022

Sept. 12, 2022

We have passed the year mark since we've had our OCN, FCC FRN and such registrations for S/S support. I got a bill from NANPfund.com / Welch LLP that has me suspicious. We don't have our own numbering and its saying this is the Annual Fee for the Numbering Administrations Cost. The FCC FRN website shows that we don't have any fees due. I'm not sure if there are ongoing costs from NECA for our OCN. I just want to make sure this isn't a fake invoice that was scraped from public FCC data. ~Jared

Disconnect without explanation
by neimanpinchas＠gmail.com Sept. 5, 2022

Sept. 5, 2022

A customer of mine had a Belgium number at Anveo, all of the sudden they disconnected the number and refuse to give him an explanation. and the ticket has been forcibly closed. Any ideas of what could be done? Below is the ticket Where did my Belgium DID disappear??? 3238082748 the number is not working and is not finding it in my account - The number was disconnected by the carrier for service abuse. which kind of abuse???? im paying for Belgium DID and channels. i dont get this, how do you shut off a number with out notification??????????? The number was disconnected according to Anveo TOS and it cannot be resinstated. We consider that questions raised in this ticket were answered in full and thus this ticket is closed. If you have additional support requests then please submit a new support ticket. Since the number was used for regular commercial usage, I am wondering how and where this could been explained, and have the number instantiated (except the ticket system) Thanks

Service notification lists (outages, etc)
by caalvarez＠gmail.com Aug. 31, 2022

Aug. 31, 2022

How do you smaller players maintain lists to notify people of issues, planned outages, etc? We can't get them to update 911, let alone who should get these. Right now it's rather manual in our CRM. It would be nice to send something out to the list say yearly, and ask them to update themselves with new employees or whatever. For frame of reference, we're very small and would notify a couple hundred people, with events less than monthly.

We are suddenly seeing a lot of this seemingly nationwide from Bandwidth and thinQ (which is a multi-carrier aggregator). Anyone else?
