Narrative:
Captain and first officer were assigned 11000 ft altitude at plesant intersection on arrival to phx. Upon reaching 11000 ft, ZAB asked our altitude, and began to alter our heading several times. Radio xmissions with ZAB became erratic. We were then cleared to continue arrival. The tone of voice at ZAB started us to question our assigned altitude. No response from ZAB.
