Of note with this. Only the voice pulse lines have intermittent issues calling some numbers.
Been trying to find a problem. This may be the cause.
McLeod is a third string voice provider in the grand scheme of things, but they should have plenty of interconnects to the POTS network to route that call properly. Almost everyone in VoIP buys numbers from someone else. That's why Level3 showed up for your other lines. It keeps the VoIP provider in numbers across the country and keeps Level3 in easy money.
For your problem, gotta narrow it down. IntraLATA, InterLATA? Specific exchanges or specific numbers? SIP to SIP? SIP to POTS? Cross carriers? Or the ever so fun forward to external number that happens to be international.
