[cisco-voip] Porting numbers between carriers

[Lelio Fulgenzi]

I was surprised when this happened to me during our first porting exercise. 

>From what I understand, there is a routing table of numbers, which tell a switch where to send a call. 

But there is also a local routing table, or list of physical termination points, can't remember, on a local CO which over ride a call being sent out into the cloud to be routed accordingly. 

When this happens, everyone who is not on the PBX that the number originally existed on will be routed properly. This means, company B has done their job. Everyone who is on the PBX that the number originally existed on will be routed to the old destination. This means, company A did NOT finish the porting properly, by pointing the numbers they were supposed to port into the cloud. 

Now, who's responsibility is it to push company A to finish their job? I think it still has to be company B. 

Carriers hate porting numbers. And they do very little to make it a smooth process.

Good morning, 

Is anyone familiar with the process of porting telephone numbers between carriers? 

I've recently ported 40 numbers from "Carrier A" to "Carrier B". Carrier B now has the numbers in their system and most callers to those numbers are getting to us via our SIP trunk with Carrier B. 

However, callers on local POTS lines with Carrier A are still reaching us via our existing PRI with Carrier A. 

Carrier B says the porting is complete; Carrier A says B has not completed the process and that is why the numbers are still active with them. 

Aside from me riding Carrier B every day to figure it out, what magic is involved behind the scenes here? I miss BGP.
