Dear H.450-Experts,

let me please put 2 questions concerning the H.450 Supplementary Services.

H.323 says that the support of H.450 is optional. How shall a H.323 terminal not supporting a particular H.450 service react on receiving an unexpected signal or apdu respectively?

Is H.450 Call Diversion restricted to H.323 terminals or is it also permitted to divert a call to a terminal which can exclusively be reached via a gateway? In the latter case: shall the gateway omit any restriction checks, going

on the assumption that the diverted-to telephone number is correct / reasonable?
