Voice chat in Gmail

Gmail has brought about a huge disruption to email services, and the constant rollout of new features leaves us dazzled. Gmail has been striving to integrate with Gtalk, and apart from voice chat and online file transfer, Gmail can now completely replace Gtalk. Today, I saw on Hun Lian's account that Gmail has added the feature of online voice chat, so I hurried to try it out. It turns out that it is just a shell.
