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

[Mike Hammett]

I don't trust last mile networks to reliably deliver SIP calls. I usually end up putting them into VPNs, TLS, etc.

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




Beginning early yesterday, we're seeing dropped voice rtp traffic to some of our business customers in the Los Angeles metro area on Frontier Comm broadband fiber. The voice udp stream is leaving our data center and never making it to the Frontier fiber customer. It's not all of our customers, only random ones. We've sniffed the traffic on our side and see the voice rtp stream leave our data center but then sniffing on our customer's side the traffic never arrives (multiple Frontier fiber customers with this issue, not just one). 


Switching the customer over to an alternate Internet connection resolves the issue. 




Frontier frontline customer support doesn’t get it and they just want to roll a tech out for an issue that’s deeper inside their network. 


We have packet captures of both sides (our DC and your customer) showing the voice rtp stream leaving our DC and never showing up at the fiber customer. 


This doesn’t seem to be affecting every fiber customer in the Frontier footprint, it just seems to be random customers. 


Anyone else experiencing this issue? Any thoughts on who to contact on the Frontier side to get it resolved and/or get some eyes on it? 


Thanks for the help.
