Even though VoIP networks are evolving and becoming predominant, TDM assets keep on significant in the networks of medium/large operators and their relative replacement is going to take a long time.
At the same time most of large/medium enterprises are renewing their infrastructure toward all-IP in order to take advantage of the enhanced features based on Unified Communication solutions. Nevertheless, a lot of TDM devices like small Local Exchange, ISDN PBX, and Fax, are still present in their networks and have to be integrated with the more recent and innovative IP-based platforms, saving the investments originally done.
NetMatch-M – the Media and Signalling Gateway within the NetMatch product line – well fit in this scenario as it has been designed to ease the TDM adaptation toward any kind of IP Multimedia Interconnection.


NetMatch-M is a multi-functional equipment for guaranteed-QoS Network Interconnection, enabling smooth Migration to “all IP”, supporting many different types of audio codecs.
By supporting signaling adaptation (SIGTRAN protocols) and the relevant Signaling backhauling capability for both SS7 and ISDN PRI signaling links it is well fitted for smooth migration of legacy TDM networks to IP networks.


NetMatch–M is flexible and scalable passing from a low-density to an high-density VoIP gateway configuration. For this reason, it is ideal for a small capacity as well as for an high capacity deployment, both for a centralized and a distributed architecture.

The most relevant features are:

  • Media Gateway functionality controlled via H.248
  • Up to 20 STM1’s in High Availability configuration
  • Support of the following audio codecs: AMR-WB G.722.2, AMR, GSM-EFR, G.711, G.722, G.723.1, G.726, G.729AB, T.38 Fax Relay, iLBC
  • Signalling Gateway (M2UA, M3UA,IUA)
  • Up to 160 SS7 signalling terminals, up to 1,270 PRI backhauling or a mix of them
  • CAS/R2 signalling
  • DTMF detection/generation
  • FAX/T.38 interworking
  • DSCP marking
