Voice Over IP Community

Voice Over IP (VOIP) is a general term for delivery of voice communications over IP networks such as the Internet. Please consult Wikipedia for an extensive description of VOIP.

In the past years around the world several experimental SIP/ENUM/VOIP-exchanges became operational and the first VOIP peering-traffic, although still in relative small volumes, started to flow over public Internet Exchanges.
Voice operators started exchanging their voice traffic in a on-net Community on a closed wallet basis, similar to traditional Internet peering.


Voice IX NL-ix, as one of the largest European Internet Exchanges, took the initiative to facilitate Layer-2/3 exchange for the VOIP community in the Netherlands by introducing VoiceIX.

VoiceIX is unique in Europe since it is the first dedicated exchange where concurrent SIP/ENUM/VOIP communities and federations can provide voice peering and carrier services to their participants.

VoiceIX makes exchange of voice traffic more easily, more scaleable and much quicker, at lower cost and at higher quality.

Moreover participants, generally voice carriers or large voice access providers, can more professionally and cheaper interconnect, where all parties can benefit from a large base of already NL-ix connected companies in a open an neutral environment, available in many datacenters in the Netherlands.

IP Telephony

Most VOIP carriers and providers in the NL-ix VOIP community offer IP Telephony services, which can be delivered over the NL-ix BandMarket service delivery solution. See our BandMarket Product Guideline how this solution can be composed.

For service Providers

For VOIP carriers it is interesting to distribute services to 30+ datacenters and reaching over 240+ members without building a private network.
See our Pricing Sheet for current BandMarket service distribution charges.

For existing NL-ix members

For existing NL-ix members it is interesting to have access to the services of a diverse group of voice service provicers in the VOIP community.

OnePort™ concept
As almost all of our services, the VoiceIX exchange services and IP Telephony BandMarket. services are delivered via the NL-ix OnePort™. This port is the basic product for all NL-ix Peering and Community solutions and can also be used in combination with the NL-ix Metro Ethernet solutions.

By purchasing an NL-ix Port, most of the Peering and Community services become available for free, and/or additional Metro-Ethernet services will be much cheaper. Speeds of 100 Mbit/s, 1.000 Mbit/s and 10 Gbit/s can be provided.
