Central call recording with RTP forking for IP Trade turrets
- Kiss, Mate
Solution overview
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
Why do you need the direct Verba - IP Trade integration?
Legacy TDM or IP call recorders using passive recording technology are not able to properly record the complex call scenarios in the IP Trade environment, and these systems cannot control the recording functionality directly of the dealer board like Verba does. Passive IP recorders also suffer the disadvantages of the monitor port issues:
- In complex switching infrastructure, the monitor port configuration can be a headache.
- In a multi-site network, branches where a few calls have to be recorded, requires dedicated recording server.
The native integration between Verba and the IP Trade dealer boards enable sophisticated features like:
- Deduplication of the media streams to lower the load on the network components
- Transcoding and selective voice activity detection for lower storage consumption
- Simple configuration of what to record and how
- Recording notification on the turret
- Replay and advanced search functions on the turret
- Optionally mixing multiple channels/calls into a single stream, then sending the mixed stream to the recorder

Possible deployment of Cisco Central call recording with RTP forking for IP Trade turrets:
- Single server solution: All Verba services (Administration, Recorder) are on one server. It is recommended only for a few user POC or trial deployment (10-20 users).
For the installation guide see: Installing a Verba Single Server solution - Media Repository + Recording Server: The Verba administration/storage server is deployed separately from the recorder.
