What is User-to-User Information (UUI)?
User-to User-Information is exchanging data by means of the telephony layers, when transferring calls. This can be used for incoming or outgoing calls.
SpeechFrame supports sending, receiving and forwarding UUI (User to User Information) between called and calling parties. The purpose of the User to User Information support is to pass information not pertaining to the call from one user to another. The purpose and use of that data is left to the user's application. It is used frequently in Call Center solutions
The information is transferred transparently through the network and does not have any effect on the call. SpeechFrame supports UUI for multiple protocols.
