This wouldn't automatically fail over to the next carrier since technically the call connects...just a delay long enough to cause eventual failure.
Could this be causing inbound issues as well? I have had several instances over the last few days where an inbound call appeared to drop when I picked it up, but then found the caller had left a voicemail. Almost as if the ring itself was delayed so that the call went to voicemail by the time I picked it up.
