[VoiceOps] Inteliquent/Sinch SIGTRAN outage

[Collin Rose]

Identical timeframes for us. I also asked for an RFO. Please share if you get anything.

We disabled TCAP/LNP lookups and forced all calls outbound to our Inteliquent SIP trunks (I guess maybe they don’t use their own signaling? ) and we were seeing good completion on outbound calls with this configuration. Of course inbound was limited by the down ISUP trunks to the tandems.

Happened to us as well.  No SS7 meant no ISUP with other telcos and no LNP lookups.  Both primary and secondary were down.

There is a lot of A and B geo-redundancy in their SIGTRAN design.  Frustrating for it all to go down at the same time.

They have not shared the cause with us.  I have told them to send us an RFO.  Master ticket 681772.

outage start: 2024-09-11T10:13-0500
outage end: 2024-09-11T12:58-0500
outage duration: 2 hours 45 minutes

We lost both our primary and backup SIGTRAN link to Inteliquent at 11:13 EST. Calling in they say some sort large scale outage. Anyone aware of any details ?
