ANIs flagged as telemarketer/spammer/scammer
by abalashov＠evaristesys.com Nov. 14, 2021

Nov. 14, 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/

ATA To Connect to Mitel PBX
by nate＠blastcomm.com June 19, 2019

June 19, 2019

I've only had to provide POTS termination to 1 MITEL system. I tried using Linksys/Cisco SPA and Grandstream ATA's, then finally put in an Adtran TA904 (2nd gen). The Adtran seemed to give the least number of issues with Lines getting stuck open, Echo, etc. But the (former) customer was still complaining about some issues when they closed up shop. I now need to provide 6 analog lines to hand off to an existing MITEL. Is there an ATA that's better than a TA908 for doing "Acceptable" POTS to a MITEL? Thanks, Nate

Old PA System setup
by darin.steffl＠mnwifi.com April 19, 2019

April 19, 2019

Hey guys, https://www.valcom.com/pdf/v1030c_v1036c.pdf We're trying to find the best way to interface 3 old Valcom speakers V-1030c to an IP paging system. I have a Snom PA1 but that won't work as we initially thought because speakers need 4 wires on a 24v power system. So 2 wires are for 24v power, and the other 2 are for audio. The snom only has a positive and negative output that feeds passive speakers, not active speakers like these. What is the best way to utilize these 3 speakers or should we just replace the speakers? We're trying to keep budget to a minimum for them so we would prefer to utilize the same speakers but what's the best way to power them and feed them audio using the existing 2-pair RJ11 cable they use?

Port to a fax platform
by darin.steffl＠mnwifi.com April 19, 2019

April 19, 2019

Hey all, We typically use Vitelity vFax for porting over fax numbers and use their Fax Enable device which seems to work well. We ran into a ratecenter that they say doesn't work for vFax. Are there any other providers you recommend checking with who offer a Fax ATA use the TLS or HTTP method so it's not actually using Voip for the fax connection? I really need to port this number to a fax provider and something we can still support. Thank you 507-527-xxxx -- Darin Steffl Minnesota WiFi www.mnwifi.com 507-634-WiFi <http://www.facebook.com/minnesotawifi> Like us on Facebook <http://www.facebook.com/minnesotawifi>

Toll Free and Local TNs Porting from Charter
by mark＠ringfree.com April 19, 2019

April 19, 2019

Hi all, Wondering if anyone has experienced the following behavior. I attempted to port both Local and Toll Free TNs from Charter, on the same day, to my usual carrier, and was advised by my carrier that Charter uses a unified system for local and TF ports, and that due to this creating an issue where a pending order would be created on the single account by virtue of dual ports, the ports could not be completed on the same day. My carrier advises most other losing providers treat local and toll free TNs in totally different systems, so this issue only affects Charter numbers. Has anyone experienced the same porting local and toll free numbers from Charter? Thanks for any input. Mark

International call "looping" post-call?
by mwiles＠akabis.com April 18, 2019

April 18, 2019

A customer came to me with a somewhat strange problem. He reports they'll be on a phone call to Jamaica (or other World Zone 1 / International destination). The called party will end the call... and he'll report hearing the last 15-30'ish seconds of the conversation "looped". It almost sounds like someone's maybe doing TCP on the RTP, and something screwy going on with the packetization. Anyone else heard of this or have a theory? Thanks! Mark

Verizon Wireless Static
by richard＠teraquant.com April 17, 2019

April 17, 2019

Have you been able to listen to sample calls containing the static described by your customer? Another potential cause, in addition to the obvious RF signal strength, could be clock slips. This is a phenomenon being derived from the wireline network rather than the radio network? and is pretty constant and loud when it happens. If the call goes over circuit-switched path, ie a ?TDM link, it can suffer from what sounds like static, crackles with about 20 ms periodicity Just an idea because poor signal:noise ratio is not normally described in the same way as the presence of static Regards, Richard Jobson Teraquant Corporation ph: 719 488 1003 d/l: (719) 766-8523 www.teraquant.com Info at teraquant.com Network Monitoring and Service Assurance - Speech Quality Experts (PESQ/POLQA) and Active Testing - Reporting ?

Feeding scripts to bwcli
by jlam＠credil.org April 15, 2019

April 15, 2019

Is there any way bwcli (Broadworks CLI) can read from standard input or give it the path of a script as a command line or prompt line argument? This person is using expect: https://stackoverflow.com/questions/46244034/executing-expect-command-with-… . I'll give it a shot, but I was wondering if there was an even more straightforward way. -- Make innovation easy http://www.credil.org/
