shared-appearance feature
MSS V23 was released yesterday. The main feature of this version is “shared appearance”. In one number service, the SIP phones can subscribe others’s dialog status, and MSS will notify them with all kinds of busy signals: early, confirmed, terminated, and so on.
Please note that this feature requires SIP phones to have SUBSCRIBE/NOTIFY capabilities. If your phones cannot support these methods, this feature will be discard automatically.
You need configure nothing to enable this feature. So easy, right? Hope you can enjoy it!
