Hello,
This is in regard to old-school POTS (copper) landlines.
When dialing long distance, we get "fast busy". Our long distance company said that Verizon, the local carrier, has the PIC code set incorrectly on the line. It needs to be set to 0555.
For context, if you remember numbers like 10-10-555-1-area code-number, the 0555 part is the PIC code and overrides the long distance company for that call. By having Verizon set the PIC code, it chooses which long distance company to use when just 1-area code-number is dialed. We're still able to fax by putting 10-10-555 in front, in fact.
A "PIC freeze" could be requested from Verizon, to stop "slamming" where your long distance company was changed without your permission. For example, if you entered a sweepstakes, the fine print might say you agree to use a long distance company with exhorbitant rates; the PIC freeze stopped that from happening.
With that history lesson out of the way, the issue is we need any PIC freeze removed, and the PIC code set to 0555 on our line. When calling Verizon Support, no one knows what a PIC code is or how to set one. If you search the forum, other customers have had the same issue. Please answer how to escalate to a part of Verizon service who understands landlines, or DM for contact information.
