Calltrunk is all about "phone conversations as a searchable information asset".
They keep it simple and device agnostic so you can make a call on your smartphone, in your browser, with Skype or a landline, and then Calltrunk stores your recordings in the cloud in your own secure "trunk" for access from anywhere.
The search feauture is powered by ARGOSearch which allows you to search your conversations for spoken words, phone numbers and dates associated with a conversation (i.e. the audio recording, call notes, transcriptions, and meta-data).
Calltrunk is used in business/enterprise and individual applications. Although recording all your phone calls is not yet common practice for many people, their customers have great things to say about the benefits of capturing conversations.
