In addition to email and cached Web searches, the DakNet technology also enables villagers to use a phone and phone number to send and receive voice messages to and from any phone by leveraging a combination of Voice Over IP telephony, traditional wireline telephony, and SMS capabilities. This VoiceMail Over IP (VMOIP) solution turns each village PC into a virtual phone booth and local exchange for limited mobility handsets. VMOIP enables users to create VoiceMail boxes through which they can send and receive VoiceMails to and from cellular and wireline phones. Using the simple numeric interface of a standard telephone handset users can communicate in their mother tongue with everyone they know who has a phone number. Since it does not require a PC interface, the VMOIP system reduces the user literacy requirements for digital communications while plugging users into traditional phone networks.

Users can send and receive VoiceMails through a publically available phone at each village PC and also use $12 cordless phones to access their VoiceMail within a limited radius from each village PC. Village PCs route VoiceMails in a store-and-forward mode until they reach a real-time Internet link, at which point each VoiceMail is routed to a server that delivers the VoiceMail to its destination phone number. For VoiceMails sent to mobile phones, SMS messages can be sent to notify recipients to call a number to retrieve the VoiceMail. For VoiceMails sent to landline phones, VoiceMail can be delivered over the phone in their entirety to the recipient or just a preview can be delivered with notification of how to retrieve the complete VoiceMail. Typically, VoiceMails for local numbers are delivered over standard telephony networks, and national or international VoiceMails are delivered using VOIP. VMOIP users can have phone numbers in multiple locations where First Mile Solutions provides servers that are closer to the people with whom they want to communicate. Village PCs with real-time broadband uplinks can also support standard VOIP communications.
