96. Support for VoIP IEs by VoIP Solution

What "Data" category information elements (section "Information Element Table") are obtained for VoIP depends on the type of device and VoIP client used, as detailed below.
The "IP capture" column represents the various IP data capture mechanisms used by TEMS Investigation connectable devices:

ODM IP capture (Android devices)

Qualcomm IMS reporting (Qualcomm IMS client)

Qualcomm DPL log message reporting (non-Qualcomm IMS logging).

With (most of) the VoIP clients found in the remaining columns, additional IEs are obtained besides the generic "IP capture" IEs.
