Quick Overview

Sangoma D150 PMC card with 400 sessions

Sangoma D150-PMC-400 Information:


Most IP telephony applications require the use of multiple types of voice codecs, which are used to digitally compress voice signals, to save on bandwidth requirements. While voice signals from the Public Switched Telephone Network (PSTN) always come in the form of the G.711 codec.


The VoIP terminal equipment and networks support a variety of different voice codecs including such as G.729, G.726, AMR, G.722, iLBC, etc. VoIP infrastructure most often needs to include the capability to mediate between endpoints supporting different codecs, yet this functionality often requires digital signal processing tasks that are often costly, resource-intensive and can affect the quality of the voice signals if it introduces too much latency and delay.


The Mezzanine Card (PMC) allows hardware manufacturers to integrate the D150 transcoding solution via the PMC standard (IEEE 1386)

30 to 400 transcoding sessions
