The integration between the Verba and IP Trade systems is based on duplication of media stream in the turrets. For each call, the dealer board system creates a copy of the associated in-bound and out-bound RTP streams. These are sent to the voice recorder server which records and archives the live feed.
The transmission of call detail information (CDR) and the negotiation of the RTP session parameters are performed using an XML protocol co-developed by IP Trade and Verba back in 2007.
The dealer boards handle special call scenarios that require special handling on the recorder side too:
- Several calls can be active simultaneously on the dealer board, these are recorded separately
- A dealer board can register on the IP telephony infrastructure with single or multiple directory numbers, all of these are captured
- Call durations can vary from seconds up to several hours (e.g. open lines), all these are recorded as expected, with silence suppressed in long calls
