Testing DTMF to known conference numbers
by compuwizz＠gmail.com March 19, 2020

March 19, 2020

At the end of the day yesterday I decided to test our product to make sure that our customers could reach conferencing services and not get FAS, excessive PDD or DTMF failures especially to international destinations. I went through old calendar invites that had a link to extra numbers for Microsoft Teams, Zoom, and an Iowa Freeconferencecall.com number. I'd like to test Cisco Webex but haven't found an invite with extra numbers for them yet. I don't know if the list of numbers are meant for public consumption or if the client is charged per minute of the call even outside of the conference room. Yesterday Simwood's blog highlighted what they were doing for their customers which included creating a jitsi meet instance (opensource webrtc videoconferencing and screen sharing software) on their infrastructure. https://blog.simwood.com/2020/03/remote-working-at-simwood-free-stuff/ I did the same for our customers as a beta "If it helps and works, I know little about this so no guarantees" service. Our small clients were very grateful so we'll see how it goes. If anyone manages a large conference service that I'm overlooking and either publishes numbers publicly, I'd like to test to make sure calls complete as expected (at a random time not the top and bottom of the hour). In an ideal world this would be a good use of a voice peering fabric but I understand call compensation and regulatory issues can get in the way of those orgs being successful. ~Jared Geiger

NENA SIP Marking Specifications
by ml＠knight-networks.com March 18, 2020

March 18, 2020

I have been working to deploy a new private WAN for a customer that services E911 emergency calls delivered over VoIP. While working on this, I learned that their DSCP markings for SIP control traffic are AF12, not AF31 or CS3 which is what I typically see from our other enterprise customers. Media is still marked EF. These markings appear to have been standardized by a body called NENA, National Emergency Number Association. Googling 'NENA SIP "AF12"' returns the relevant PDFs. Below is a sample from their standards guide. DSCP | Use | PHB -----+----------------------------------+-------- 0 | Routine Traffic | Default 1 | 9-1-1 Signaling | AF12 2 | 9-1-1 Text Media | AF12 3 | 9-1-1 Audio Media | EF 4 | 9-1-1 Video Media | AF11 5 | 9-1-1 Non-human-initiated Call | AF21 6 | Intra ESInet* Events | AF21 7 | Intra ESInet Other 9-1-1 Traffic | AF22 (* Emergency Services IP Network) Does anyone know the reasoning behind specifying SIP as AF12 instead of AF31? While developing these standards, was NENA aware that AF12 tends to be prioritized lower than AF31 on most networks? Just trying to get some background on the decision. Thanks, -Brian

PSTN Info
by ross＠tajvar.io Feb. 26, 2020

Feb. 26, 2020

Hi all, I am looking for some resources to help me understand how to interact with the PSTN more directly. I have worked for companies which offered VoIP service, but we've always used other carriers upstream (e.g. Bandwidth, Flowroute, etc.). I've found a few references to the regulatory process (e.g. https://transnexus.com/whitepapers/how-to-get-an-lrn/) What I'm looking for is a technical description of the equipment required and how it works. Does anyone know of any good references for this kind of information? Thanks, Ross

Did the Do Not Originate Registry trial a few years ago ever become a real thing? How does a carrier get access to this data?

NTP Question
by voiceops＠ics-il.net Feb. 18, 2020

Feb. 18, 2020

How many NTP servers do you guys run? I just spun up two NTP servers in different locations on this network. Metaswitch just asked me for at least four (preferably five, or even more). Right now, the ones I have are just referencing the US pool. Eventually, they'll reference on-net GPS-backed devices. Is having four VMs running NTP a ridiculous proposition (well, other than resources, which it'll consume very little)? I should be able to work out putting them on four different physical servers at the moment, but I don't know that we'll have four or more physical servers once I get new ones (and consolidate). Thoughts? ----- Mike Hammett Intelligent Computing Solutions http://www.ics-il.com Midwest Internet Exchange http://www.midwest-ix.com
