In environments like retail or home office where no space for a PC is available or you do not want to keep a PC running all the time (notably to avoid the risk of someone accidentally switching off the PC thereby taking away the voicemail service), Embedded Voicemail may be the preferred option to enable an entry-level voicemail service. On the IP Office Small Office Edition and the IP406 V2, Embedded Voicemail can be installed to provide an entrylevel voicemail service. With the Small Office Edition this solution does require a voice compression channel for each call that it handles. The maximum number of messages stored is only restricted by Embedded Voicemail cards storage capacity (currently around 10 hours on the Small Office Edition and 15 hours on the IP406 V2).
