Calltrunk is a self-service call management and call-recording solution built on the OP3Nvoice platform for consumers and corporates.

[2] The company was started because the Calltrunk founders personally needed a cloud-based call recording service.

The software, available for computers and mobile devices, enables users to record phone calls and search them for verbal information.

[5] Subscribers store spoken data from mobiles, land lines, Skype or a dictaphone, and upload them into an online storage bank.

[6] The technology can struggle to cope with background noise and some regional accents, resulting in accuracy rates too low to make services acceptable to a mass audience.

[7] Calltrunk's products allows users to share and/or make recordings with Evernote, Box, Dropbox, Sugar CRM, download or order transcriptions.

All CallTrunk recordings can be accessed online via a browser or via Call Trunk's iPhone app.

[4] Anthony Lee, data protection and privacy expert at law firm Bircham Dyson Bell, agrees, but only up to a point.

Calltrunk disagrees and believes the law is analogous to that covering email, which, technically speaking, requires the consent of the sender before you can forward it.
