Voice Services data and the TAPI server
To use the prompt/collect digits feature, you must have Symposium TAPI
Service Provider and Symposium Agent installed, or another agent software that
is compatible with Symposium TAPI Service Provider. The prompt/collect
digits treatment can be used to send collected digits to a TAPI server to enable a
data screen pop (for example, using Symposium Agent software).
Sending data to TAPI server
The file TAPIIVRConnection.dll ensures that data is sent successfully to the
TAPI server. It provides a selection of APIs that are used by the Voice Services
service to establish and maintain a connection to TAPI Service Provider, and
also to construct call data messages to enable digit transfer from Voice Services
and TAPI Service Provider.
TAPI SP IVR Messages
Voice Services uses two primary messages to communicate call data to TAPI:
IVRCallerData
!
IVRCallerDataResponse
!
