Recording on mobile devices is more complex than recording on fixed line devices. A fixed line device always has a guaranteed network connection, whether that is IP or TDM. Therefore, the network connection can be tapped for recording purposes. This network tapping is carried out at a network level and is outside of the end-users control, meaning that tampering and disabling are not possible.
Mobile recording is inherently more complicated as the end-user has a device that is not physically connected to any network. Many regulations state that all calls (and other media types such as text and messaging) have to be recorded, therefore, solutions must be tamper-proof, able to record inbound and outbound communications (voice and text), and work wherever the user is located (home network or roaming).
The chart below outlines many of the historical approaches for recording mobile phones along with the advantages and disadvantages of each approach.
CTI Group is noticing a trend towards the adoption of mobile recording as an OTT service. This is being driven by recent compliance regulation in the financial services sector that specifically requires trading firms to record trades which are undertaken on mobile devices. Compliance examples include, the Dodd Frank regulations in the US and Financial Conduct Authority (FCA) regulations in the UK, but. this is a global phenomenon with regulation beginning to come into force through Asia Pacific and Europe.
