voip.ms Outage
by aaron＠heyaaron.com Sept. 20, 2021

Sept. 20, 2021

Looks like voip.ms is currently under DDOS attack. I have a few DIDs through them. Calls ring for about 30 seconds and then get an error message about being unable to complete the calls. DIDs that have a 'fallback' number or recording are working properly. Outgoing calls are just dead air and never complete. https://twitter.com/voipms -A

SMS Spam from 77088 Amazon Alerts?
by beckman＠angryox.com Sept. 4, 2021

Sept. 4, 2021

In the past 3 days a single end user has received 3 SMS messages from a US Short Code 77088 that is registered AFAICT to Amazon Alerts. The end user has forwarded the content to us. I have replaced the '://' with '___' and the URL path also with '___' to prevent people from clicking on the link and hiding important info if it is legit. But I don't think it is legit, because it is a whole bucket of weird. 7babf08dit-t77088/TYPE=PLMN2.E?http___d2.2c1.cz:80/7bab___ditX3/38 7b4a0e58Yy-t77088/TYPE=PLMN2.Ehttp___d2.2c1.cz:80/7b4a___8YyX3/92 7b0c2c36sr-t77088/TYPE=PLMN2.E:http___d2.2c1.cz:80/7b0___36srX3/730 The SMPP server is noting that the encoding is "8-BIT" which is an odd encoding that I haven't seen before. This domain in the SMS IS hosted by AWS DNS (Route 53), and the domain is registered to someone in Massachusetts, US. Yes, the end user can send STOP to 77088, but at least one of the messages did seem to come from Amazon. Is it possible that some service is allowing someone who is NOT the owner of 77088 to send SMS messages pretending to be 77088? Did someone get into Amazon's account or 3rd party account? It is very strange to see this coming from a Short Code.

STIR/SHAKEN concerns
by marylou＠backuptelecom.com Aug. 21, 2021

Aug. 21, 2021

I am doing some research for an article so I wanted to ask all of you some questions about STIR/SHAKEN and the upcoming implementation in late September when traffic will start getting blocked. I personally envision the first few months will be a nightmare! Ironically this will all hit just as elections are about to take place......how convenient! When the industry missed so many steps on the implementation phase, there's sure to be things they've missed in this phase so let's think ahead so we can address as many problems as we can before they happen! I specifically want to focus on the effect the changes are having and will have on end user customers. Not only residential and small business customers, but enterprise customers such as schools, hospitals, banks, political organizations, and other industries that use call centers. Please respond to the questions below and let me know your thoughts. 1. Have you seen any changes in the industry since the June 30th implementation date. I have witnessed a few odd routing issues that have never happened in the past. I'm not sure if they are a fluke or a trend. Have you experienced anything out of the ordinary? 2. If your network is partially TDM and partially VOIP, have you experienced any issues with either of them? What are your future concerns since STIR/SHAKEN does not work with TDM? 3. My biggest complaint as a residential consumer is that caller ID no longer shows up like it did. Unless I have the number in my phone, I only see something along the lines of Scam Likely or a phone number with no caller ID. I find this quite irritating since it prevents me from determining if its a friend whose carrier hasn't implemented it yet or an actual scammer. Anyone else have complaints about what information is being passed? 4. Are you getting more complaints from your customers about anything related to STIR/SHAKEN? What are the nature of the complaints? Is there a recurring theme? 5. What is your customer's impression of what a Robocall is? My son claims he's getting more SCAM calls than he was before but I'm not sure he understands what a Robocall is. He may consider any advertisement or donation request a robocall, but some things are allowed while others aren't. What are you doing to help your customers understand what's allowed and what's not allowed? 6. If you're hearing from customers about scam calls they are getting, are you reporting those calls to anyone? If so, who are you reporting them to? 6. Criminals always seem to be creative. Have you seen any new methods scammers are using to get around STIR/SHAKEN process? 7. One of my greatest concerns I have about the September implementation is that carriers will get no warning if/when they are going to be blocked. I haven't seen anything that states a terminating carrier or intermediate carrier has to give a warning muchless disclose that they will start blocking another carrier's traffic. Maybe there is a hotline to call if your traffic is being blocked unjustly, but I haven't heard of any. Have you? Normal routing issues are already a nightmare to deal with. Hopefully this will not make it worse or just another method for anti-competitive carriers to take out their competition! 8. The last question leads me to the next one. I know there are some carriers using their underlying carrier's certificate so they didn't register for the Robocall Mitigation Database. I didn't recommend this, but I heard through the grapevine some consultants / underlying carriers did. If those who didn't sign up for the Robocall Mitigation Database have legitimate traffic shut down, what will happen to all their legitimate customers? Will they be out of service until the ITG gets around to figuring it out? Has anyone heard of a plan to address the impact on consumers displaced by this? 9. Has anyone heard of a centralized contact to deal with unjust blocking complaints? We all know nothing goes perfectly but I would think it will be important for everyone to know what number to call should they have problems BEFORE this change is implemented. Have any of you heard anything? I haven't! 10. I tried to keep my list simple but I would love to hear your thoughts on anything I missed. Thanks for all your input, MARY LOU CAREY BackUP Telecom Consulting Office: 615-791-9969 Cell: 615-796-1111

Strange Inbound Verizon Issues
by mwiles＠akabis.com Aug. 17, 2021

Aug. 17, 2021

We are seeing an issue involving Verizon... wanted to see if anyone had thoughts... or if Verizon's monitoring here... The problem seems to be happening only in FL, but I could be wrong about that. A Verizon customer calls a TN we have via Inteliquent. They get the following intercept message: "Welcome to Verizon wireless. Your call cannot be completed." Here's where it gets interesting... we have a technician standing next to the customer with the Verizon cell that's failing. The technician calls, using his Verizon phone, and it always completes. The customer, standing less than six feet away always fails... again, both calling the same terminating number. We can only come up with one difference... when we get the failures, the Verizon phones being used are all personal accounts... and the ones that complete are on Verizon business accounts. I'm not saying that's the cause of the issue; but, it's the only common denominator we can find. We tried to open a ticket with Verizon, as the calling party (personal phone), and Verizon wouldn't open a ticket. (what the heck???) Has anyone seen or heard of such a thing? Thank you, Mark

Anyone from AT&T (BellSouth) able to look at some number reachability issues?
by hf0002+nanog＠uah.edu Aug. 12, 2021

Aug. 12, 2021

If anyone from AT&T (especially the old BellSouth area) is here, maybe you can save our wretched souls. It appears AT&T customers suddenly can't call any of our numbers as of this afternoon, instead receiving announcement "Your call cannot be completed at this time." Seems to apply to AT&T Wireless customers, as well as AT&T fixed service (VoIP/PRI) customers. I suspect this is due to the fact that our numbers were previously with AT&T (delivered on a handful of PRIs) but were ported out to Comcast about 2 years ago. So obviously I cannot open a ticket with AT&T, not being an AT&T customer. Comcast has already concluded there is not much they can directly do about this. The affected numbers are 256-824-1000 through 256-824-7999 (total of 7,000 numbers). Any and all assistance would be greatly appreciated! -- Hunter Fuller (they) Router Jockey VBH M-1A +1 256 824 5331 Office of Information Technology The University of Alabama in Huntsville Network Engineering

ANI Network trouble

Aug. 11, 2021

ANI Network seems to be having a bad day. Some calls complete quickly, others have a long PDD before a 503 reject. Called the NOC to open a ticket and the person said they are having lots of issues ongoing.

Enterprise Connect Orlando

July 21, 2021

It has been many years since I attended Enterprise Connect - I think the last time was back in the early 2000s. Are other members of the group attending the conference? Is it helpful to CLECs and UCaaS Providers? Should I buy a full pass or just the expo pass? Ryan

If anyone from Spectrum is watching I'd send them a bottle of booze for their help (or case of beer) (or flowers).. We have a domain that keeps getting blacklisted by their DNS (Meaning it won't resolve). It's been an on again off again issue, and we have no idea why.
