Which two of the following must be configured to allow users to bind transfer calls to both internal and PSTN numbers using H.450.2 supplementary services? (Choose two)

A.
transfer-pattern .T

B.
transfer-system full-bind

C.
supplemental service h.450.2

D.
allow-connections h323 to h323

Explanation:
To configure CME to permit transfers to nonlocal destinations, set the transfer-pattern command under telephony-service. Using .T provides full wildcard matching for any number of digits.
To configure CME to use H.450.2 transfers, set transfer-system full-consult under telephony-service command mode. This will turn on H.450.2 and H450.12 services.
