Overview

The integration between the Verba and IP Trade systems is based on duplication of the media stream on the turrets or TPO side. For each call, the dealer board system creates a copy of the associated inbound and outbound RTP streams. These are sent to the voice recorder server which records and archives the streams. 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

Deploying BT IP Trade Recording

The following section contains all the necessary steps for setting up a BT IP Trade recording infrastructure.

For BT IPTrade deployments, the Recording Director and Media Recorder roles cannot be split out to different servers. These 2 roles must run on the same Recording Server to avoid limitations around failover design inherit in the IP Trade recording protocol design. This means that the Recording Servers must be allocated across the turrets and there is no dynamic load balancing available.

Server Sizing

Allocating the appropriate resources to the different servers is crucial. For guidance, see Server sizing and requirements

Preparation

Make sure that all the required prerequisites are installed on each server prior to the installation.

For guidance on configuring the necessary firewall port, visit Firewall configuration for BT IP Trade recording deployments.

Installation

The following articles contain all the step for installing the various server roles:
