Verizon Wireless Contact
by cwhelan＠staff.gwi.net Jan. 21, 2022

Jan. 21, 2022

Hello everyone, I know this is a long shot, but I'm hoping someone on here works for Verizon Wireless or knows someone that is in a position to assist us. Recently, a change to call routing occurred and Verizon Wireless calls are now being delivered across our tandem instead of a SIP peer. Ideally, I would like to establish a SIP trunk to Verizon Wireless but changing the call flow is the short term goal. Thanks in advance for your help!

ANIs flagged as telemarketer/spammer/scammer
by abalashov＠evaristesys.com Nov. 15, 2021

Nov. 15, 2021

Hi, So, of course, it is a known problem in the legitimate side of the lead engagement call centre, survey, etc. business that ANIs get flagged as "telemarketer" pretty quickly and start showing up that way on people's phones. Your normative viewpoint on that may vary depending on what you think of lead gen calls, but regardless, a reasonable person would differentiate between: (1) Legitimate outbound dialing operations that are following up with leads who provided their phone number and agreed to be called (at least, as a matter of clicking "accept" on _something_), or for some other legitimate mass-dialing purpose, and who actually own the DID inventory from which they present local-market ANIs and can in fact be reached on those numbers; (2) Illegal spammers who use fake ANIs and call people who did not in any way consent to being called by them. I am trying to learn a bit more about how this is done and what a legitimate, above-board business can do about it. Ignoring the factor of third-party call-screening apps (which most people with a mobile don't use), where is this generally implemented? As I understand it, T-Mobile do it on the network level. I have T-Mobile myself, and probably 2/3rds of unfamiliar numbers, including quite legitimate ones, show up as "Scam Likely" ? I know that's come up on the list before. AT&T displays "Telemarketer"; do they do it that way too, or do they use a Google Android feature for that which they enable as part of their carrier defaults for carrier-issued phones? What about other carriers and Android? As far as I know, Apple don't do anything like this. Do people with iPhones just not receive this "service"? How does that work? Asking where the central, or the most influential authority lies and who provides it goes to the heart of the real question, which is: what can a legitimate business do if their number has been blacklisted this way? As I understand it, the maintainers of these lists, along with the criteria for getting on them, are elusive and inscrutable, and there's really no recourse and no appeals process. I furthermore understand that this has led to the widespread approach of rotating ANIs, but that's a losing battle; they get flagged too. I imagine it won't be long before the criteria for "Scam Likely" are just "number appears to call lots of numbers in this rate centre and otherwise hasn't been around very long". But this is all just conjecture on my part; I really don't know much about how my carrier, anyone's carrier, or some BigCo that's behind my mobile OS decides that a call is a "telemarketer" or "scam" call. If anyone can shed some light on how this really works and what, if anything can be done about it, I would be most appreciative. -- Alex Balashov | Principal | Evariste Systems LLC Tel: +1-706-510-6800 / +1-800-250-5920 (toll-free) Web: http://www.evaristesys.com/, http://www.csrpswitch.com/

VoIP Provider DDoSes
by voiceops＠ics-il.net Oct. 8, 2021

Oct. 8, 2021

I sent this to NANOG recently, not even thinking that this list may get a better ROI. As many may know, a particular VoIP supplier is suffering a DDoS. https://twitter.com/voipms Are your garden variety DDoS mitigation platforms or services equipped to handle DDoSes of VoIP services? What nuances does one have to be cognizant of? A WAF doesn't mean much to SIP, IAX2, RTP, etc. ----- Mike Hammett Intelligent Computing Solutions http://www.ics-il.com Midwest Internet Exchange http://www.midwest-ix.com

thinQ is making hay while Bandwidth is down
by caalvarez＠gmail.com Oct. 3, 2021

Oct. 3, 2021

This seems to be a bit disingenuous. I don't believe that they can multi-home or move DIDs quickly? Or am I wrong? Could they actually solve the current problem? DIDs are the only issue; we simply moved outbound.

Just as I was configuring and testing our first few SMS numbers, it has died. I can view some numbers but they show invalid info, or the site just hangs with loading bubbles.

Five9 Issues / DDoS?
by ivan.kovacevic＠startelecom.ca Sept. 28, 2021

Sept. 28, 2021

So we have a Five9 SIP Trunking client who is being told by Five9 that their IVR/DTMF isn't working because of the Bandwidth.com outage. which is strange .... because their call path does not touch bandwidth.com at all... and raises the prospect of Five9s being targeted separately from Bandwidth? Any Five9 customers who are having issues which are definitely not related to Bandwidth.com? Or is that platform specific question too obscure for this list?
