SS7 Landscape
by voiceops＠ics-il.net Oct. 24, 2023

Oct. 24, 2023

We currently get our SS7 via TNS. I (maybe incorrectly) understand them to be a big dog in that space. I've had two major problems with them in six months. What are my alternatives? Are they less pleasant? ----- Mike Hammett Intelligent Computing Solutions http://www.ics-il.com Midwest Internet Exchange http://www.midwest-ix.com

Port Away Cancel Service
by voiceops＠ics-il.net Dec. 29, 2022

Dec. 29, 2022

I have two conflicting opinions in my head (origin unknown) of what to do with the subscriber's service when they port away. In the absence of requirements, what are people generally doing? 1) They've ported a given number away, so clearly they don't want our service. Terminate the service and enact any termination provisions in their agreement. 2) Contact the customer (after the port is complete) and confirm their intention to cancel. Terminate the service and enact any termination provisions in their agreement. 3) Contact the customer (once the LSR is received) and confirm their intention to cancel. Terminate the service and enact any termination provisions in their agreement. 4) Do nothing different until the customer contacts you to cancel. 5) Something else. Number 3 seems like the one most likely to have a regulatory issue, given that you're contacting the customer during the port process, but I think as long as you don't do any retention attempts, you're alright. ----- Mike Hammett Intelligent Computing Solutions http://www.ics-il.com Midwest Internet Exchange http://www.midwest-ix.com

Empty Calls

We've been getting "empty" calls for years. BY empty, I mean there's no audio there at all. ----- Mike Hammett Intelligent Computing Solutions http://www.ics-il.com Midwest Internet Exchange http://www.midwest-ix.com

Determining Carrier for a US Short Code
by beckman＠angryox.com Dec. 13, 2022

Dec. 13, 2022

We have had a few issues in the past 24 months where a major business stops sending Short Code SMS messages to our DIDs. In all of the cases, it turns out to be a "misconfiguration" or an "incorrect mapping" with the carrier responsible for sending and receiving the Short Code SMS messages. However, we normally just go directly to our DID carrier and ask them to investigate and get it fixed, which they do, but it takes a long time, and it turns out that it isn't our carrier who is dragging their feet. Given a US Short Code, such as Citi 248487, how would I find out who the carrier is that services that Short Code? Is there a public or private database of this information? Routing table? Something similar to an LRN for Short Codes? I can find out what company owns/purchased/rents/leases a Short Code with online information, but I cannot seem to find the carrier of record for a short code. If anyone knows a list of the "major players" in the short code space, I'd love to know.

+1 368 997 Exchange shows as "Assigned" but not "In Service" (Canada)
by beckman＠angryox.com Dec. 13, 2022

Dec. 13, 2022

Customer says "I cannot call +1 368 997 xxxx" Indeed, 5 termination carriers all reject the call. CNA Reports that 368-997 is "Assigned" to TELUS but not "In Service" as of 2022-12-06: https://cnac.ca/data/COCodeStatus_NPA368.htm (filter by Exchange Area of "Calgary") It would seem that the carrier's rejection of the call is reasonable and sound, since the NXX is NOT "In Service." Who screwed up here? A) TELUS by not notifying CNA it was issuing 368-997 numbers to real customers B) Terminating Carriers by not adding "Assigned" NPA-NXX to their decks C) Yer mom D) Someone else And how does one influence the situation's repair? E.g. Termination cannot happen until the CNA updates the NXX Status, and only TELUS can update the NXX Status since it is assigned to them, so only TELUS can fix this, and if it is TELUS, who knows who in TELUS can get this fixed and how quickly?

Full vs. Partial Port
by voiceops＠ics-il.net Dec. 2, 2022

Dec. 2, 2022

Is there any advantage to us doing a full port? I figured partial port always left room for the losing carrier to still have numbers the customer forgot about. ----- Mike Hammett Intelligent Computing Solutions http://www.ics-il.com Midwest Internet Exchange http://www.midwest-ix.com
