I'm in the 409 area code & I have a user trying to call 318-627-xxxx & getting a fast busy. I've explained to the user that there is nothing I can do on my side & it maybe a phone co. issue or the other party's PBX. The user has tried 2 other of their numbers with the same result. I tested some other random 318-627-xxxx numbers & got a ring tone. Any idea what could be wrong here? My user & the other party are convinced there is something wrong w/ my system despite my best effort to explain to them otherwise.
