" they give you market entry without the technical need to establish extra homing arrangements that aren't beneficial to you."
Could you elaborate on that? ----- Mike Hammett Intelligent Computing Solutions http://www.ics-il.com Midwest Internet Exchange http://www.midwest-ix.com ----- Original Message ----- From: [email protected] To: [email protected], [email protected], [email protected] Cc: [email protected], [email protected] Sent: Wednesday, August 29, 2018 6:05:39 PM Subject: Re: [VoiceOps] LNP, tandems, etc. I've had some interesting arguments with other carriers regarding their obligation to connect to us. Oh, you aren't connected where I'm homed? Go order connectivity then. They have a little more power to make demands when you have more than 24 standing calls to them, but by and large with these stubborn providers we never do, and when they have complained i've given them a location they can install 1 way trunks to me at (as I have no desire to terminate traffic to them directly), and they always balk and find some other way of dealing with it because it was all well and good until it was their money they were spending instead of mine. The trick ends up being to never do 10k blocks when you don't have to. Thousands blocks aren't just great for number consolidation, they give you market entry without the technical need to establish extra homing arrangements that aren't beneficial to you. Sure sometimes you're the guy who has to own the 10k block, bu That's true if the ILEC has an agreement with the tandem provider. There are some little ILECs that have their own tandem and refuse to use the big ILEC tandem provider! You have to look at the routing of the ILEC switch in the LERG to figure that out.
