CDR/SMDR collection

Serial Connections

Many telephone systems output their CDR/SMDR call records through a serial interface. The ip.buffer can capture this data easily.

The automatic pin-detection, and automatic protocol analysis of our products means that installation is simple — you can use standard pin-for-pin cables without requiring null-modem adapters!

Some serial PBX connections output their data with frame markers, or in binary. The ip.buffer is equipped with the protocols required to connect to most PBX devices serially.

The ip.buffer allows you to place the CDR analysis PC anywhere on your network — the ip.buffer can forward the captured data reliably to your PC, even securely across the Internet!

Networked PBXs

The ip.buffer includes support for many proprietary PBX network protocols — including Avaya RSP, Alcatel TCP port 2533, Nortel BCM LiveStream, Cisco CCM5+ & CCME, NEC NEAX over TCP/IP, Mitel 5000, Siemens iSDX binary, Panasonic KX-TD and Philips FDCR. New protocols can be added dynamically, and in the field, through the ip.buffer's powerful scripting language.

By using the ip.buffer you can provide a rugged, reliable system for collecting CDR/SMDR data from a networked PBX and forward this data to a central PC. The ip.buffer can even send the data securely across the Internet!


As VoIP becomes more and more popular, it can be a challenge to collect meaningful CDR/SMDR records from sites.

The ip.buffer includes a broad support for VoIP PBXs that allows collection of records through TCP/IP, RADIUS Accounting records, syslog records, FTP pushes from the PBX and other methods!
