We are only announcing our local networks to each other. In the business sector, many establishments communicate with their regional offices in the middle east over the Internet. We are presently seeing over 4 Mbps traffic after establishing the peer.

VoIP. My initial feeling is even if the routing between GCC countries through US is totally inefficient from engineering point of view, but if most of the data IP traffic is really not between the GCC country, we may not care. However, if VoIP is to be a significant service, then I suspect there may be a lot of VoIP traffic between GCC countries. In which case, one may pay attention to ITU recommendation G.114 on One-way Transmission Time (note: not round trip) and its effect on voice services. It suggests to keep the one way latency to under 150 ms. 150 - 400 ms is acceptable depending on application. Anything above 400 ms is not acceptable.
