[VoiceOps] All Circuits Busy?

[Rob Dawson]

We’ve seen that mode of failure as well – 183 w/ SDP but called party never rings and then a CANCEL. Lots of complaints on otherwise normal looking calls, makes for fun troubleshooting. Peerless was taking a lot of our traffic and they do appear to have tracked down an issue with another carrier that was impacting some calls, but they are not the only carrier we are seeing the issue with. And again, I can replicate the failures on my cell phone in many cases leading me to believe it is a more generalized issue.

I missed that, but could be similar and the timing seems about right. Might be a small increase of 486's but we are generally getting 183 w/SDP ringing then treatment, CANCEL, 487 Terminated. So they "appear" like ring no answers and many may be, but some are not. And since they appear normal, it is a bit of a needle in a haystack. That said, we've chased down a few with terminating carriers and capacity, or lack thereof, is becoming a likely candidate.

I think Rob ask a similar question several days ago- back on the 18th.
Something about Generalized Call Failures?
