VoIP Gateway Testing

Voice services are not out, but they’re changing. With customers wanting more services and more flexibility, ‘triple/quadruple play’ or general multi-play is now the mantra: delivering broadband, video and fixed/mobile telephony over IP networks. Make make sure that every device involved exceeds customer expectations, while meeting every regulatory requirement.

From Analog to Digital

While gradually disappearing, POTS (plain old telephone lines) are still needed to maintain existing infrastructure that is not easily served by digital: modems for remote access, elevators, alarms, credit-card machines, etc. The technology to convert the analog systems to digital comes in many flavors, ranging from eMTA (PacketCable 1.5/2.0 MGCP NCS/SIP) to pure Analog Telephone Adapters (ATA)s. As different VoIP Gateways cater to different needs, use different protocols and must meet local specifications, count on us to help you keep up!

VoIP Gateways and Technology: how we can help

Trust our expertise in testing and validation

Excentis has a strong expertise in testing VoIP Gateways and VoIP technology in general. From testing the protocol and the physical layer to making sure that your telephony adapters (E-MTA, ATA, voice gateway, …) are compliant with the regulations in every country where you’re doing business: we’ve got you covered.

Some examples:

  • Ringing frequency, cadence and delay
  • Caller ID (FSK, DTMF, line reversal, timing, signal levels, calling name and number delivery, …)
  • Supervisory tones (dial tone, busy tone, congestion tone, ring-back tone, …): frequencies, cadences, levels, delay
  • DTMF tone detection, levels, frequency accuracy
  • Voice levels (A/D gain, D/A gain, end-to-end gain)
  • Voice quality, MOS, delay, jitter
