Which RAS message is used between two gatekeepers to resolve an alias address?

A.
GRQ

B.
ARQ

C.
IRQ

D.
LRQ

E.
RRQ

Explanation:
LRQ — These messages are exchanged between gatekeepers and are used for inter-zone
(remote zone) calls. For example, gatekeeper A receives an ARQ from a local zone gateway

requesting call admission for a remote zone device. Gatekeeper A then sends an LRQ message to
gatekeeper B. Gatekeeper B replies to the LRQ message with either a Location Confirm (LCF) or
Location Reject (LRJ) message, which depends on whether it is configured to admit or reject the
inter-zone call request and whether the requested resource is registered.
