Third Party VoIP Over Xfinity
by Matt Hoppes 14 Sep '24

14 Sep '24

I have an employee who has recently switched to Xfinity cable service. Ever since they switched their internet service their work phones will not stay registered for more than about 3 minutes. These same phones have been used on many ISPs without issues. The same config has been used behind multiple levels of NAT without issues. She was fine, until she switched to XFinity. Of course, XFinity support is absolutely worthless. Anyone from XFinity Tier 3 or such that might be able to offer assistance? I suspect it's something stupid with either NAT overload in the modem or the modem not keeping the SIP channels open. I've tried playing around with registration times without any success. And again, we've never had issues with these phones or this setup with any other ISP.

OIX (formerly Open-IX) Document Development Mailing List (Invitation to Join)
by Chris Grundemann 12 Sep '24

12 Sep '24

Hello NANOG, This message is being sent in my capacity as the Chair of the Board of OIX. We (OIX) have some proposed updates to standards documents that affect this community. As such, we would like to invite anyone and everyone interested to subscribe to the OIX DDP mailing list. The sole purpose of this OIX DDP mailing list is to discuss changes to standards and/or BCOPs within the scope of OIX. To ensure that all documents are created and updated in an open, community-led, transparent, and bottom-up manner, we need as many eyes on the process as possible. Thanks in advance - mailing list details follow. -- The OIX Document Development Process (OIX DDP) is the process by which current Standards and best current operational practices (BCOPs) for the operation of the Internet, and connected networks, are documented by the Global Network Engineering Community (GNEC). These OIX documents are developed and published in an open, transparent, bottom-up, and ongoing manner designed to yield functional documentation that is accessible to all. To support this, OIX maintains an OIX DDP mailing list for public discussions of proposed documents and/or changes to published documents. The list address is: oix-ddp(a)mailman.swcp.com If you're familiar with mailman, the various associated addresses are all there too. Most notably: oix-ddp-subscribe(a)mailman.swcp.com oix-ddp-unsubscribe(a)mailman.swcp.com To make the list name easier to remember, I have set up an email alias: oix-ddp(a)oix.org -> oix-ddp(a)mailman.swcp.com The web page for users of the OIX DDP mailing list is: https://mailman.swcp.com/cgi-bin/mailman/listinfo/oix-ddp More information can be found in our GitHub repo: https://github.com/Open-IX/BCOP Most notably: https://github.com/Open-IX/BCOP/blob/main/OIX-DDP.md The DDP itself is due for an update, and the proposed changes will be sent out to the mailing list shortly.

Re: Re: Survey on barriers for RPKI adoption
by Lancheng 10 Sep '24

10 Sep '24

Hi Sofia, I am currently an Assistant Researcher in Zhongguancun Lab, Beijing, China. Although I am not a network operator, I am very interested in this topic. Last year, I also did a survey asking network operators about the barriers to adopting ROA and ROV. That work has been accepted by NDSS 2024 [1]. I hope this paper could be helpful. [1] https://www.ndss-symposium.org/ndss-paper/understanding-route-origin-valida… Best, Lancheng >(Apologies for duplicates) >Hello everyone, >Following up on my message below, I wanted to let everyone know that we have extended the due date for the survey on barriers to RPKI adoption until Sep 19th. >If you are a network operator who manages IP space through multiple RIRs and you haven’t already participated in the survey, please take a moment to do so as we would really appreciate having your valuable input. It will only take a few minutes: >https://www.surveymonkey.com/r/CHLHLML >At this stage, we would like to particularly encourage those of you who have not created ROAs yet to understand what barriers or challenges you have experienced, as we don’t have enough representation from this group yet. >Thanks so much in advance for your input! >Warm regards, >Sofía >-- >I am sending this email at a time that suits me and the time zone I work in. Please feel free to read, and act on or respond, at a time that suits you.

CenturyLink Denver - failing hardware
by Elliott Sims 09 Sep '24

09 Sep '24

I'm attempting to get ahold of someone at CenturyLink/Quantum/Lumen about an unusual hardware failure that's causing issues for a lot of customers in southwest Denver. It appears that a buffer in one link in a LAG or ECMP group is flipping a bit around 10MB in to a zero. They have a bunch of tech visits scheduled to various people, and I assume after enough of those fail to fix the issue it'll eventually filter up to the NOC or neteng in a couple of weeks, but I'm hoping to short-circuit that a bit. Symptoms/troubleshooting: No change on home router replacement No difference across devices ICMP ping works fine, even padded to 1460 with 00 or FF SSH/SCP work (generally limited to 2MB or 4MB buffers/window depending on the version) HTTPS fails frequently Downloading a 10MB 0-filled file via HTTP succeeds consistently. Downloading a 10MB 1-filled file fails frequently Specifically, any 1-filled file with 10482846 or more bytes sees frequent failures For a consistent 5-tuple and large 1-filled file, failures are consistent.
