[VoiceOps] One Way Audio - Frontier Comm (Los Angeles area)

[Jim Rodgers]

We use SIP TLS. I don't think they're intentionally blocking voice traffic,
I think there's something broken inside their network that needs to be
fixed (lossy link somewhere?).

The issue is getting anyone there to recognize the issue and want to fix it.
