This report is devoted to the recent results of the study of the processes e+e− → KSKL, K+K−, π+π−2π0, 2π+2π−, ηγ at the ϕ-meson region with the CMD-3 detector at the VEPP-2000 collider. From the combined analysis of KSKL and K+K− final states the ϕ-meson parameters were measured, and the obtained ratio of gϕK+K− and gϕKSKL couplings was found to be compatible with the isospin symmetry. From the analyzes of the π+π−2π0 and 2π+2π− final states the branching ratios ℬ(ϕ → π+π−2π0) and ℬ(ϕ → 2π+2π−) were determined.
