[outages] Mobile calling issues - Michigan/Detroit

[Ufer, Robert]

I am seeing issues completing calls in the region – were are running our SIP trunks through Intrado and they see connection issues on the carrier side. It looks like SIP peering is broken in the Sprint / T-mobile carrier network for the region. Verizon and AT&T are working but Sprint and T-mobile DID calls are failing with a “no routes found” error.



Thanks,
