[VoiceOps] SS7 Landscape

Tue Oct 17 17:04:54 EDT 2023

Hi,

I am joining this thread late, but, would anyone out there be interested in
exchanging traffic with other carriers directly over SIP?

The service would just look like a carrier, except it would know how to
reach all other participants directly with SIP, bypassing TDM land, and
enabling rich media as a fringe benefit, as media would be direct between
endpoints.

I have a proof of concept and am wondering who out there might be willing
to do some testing.

Email me directly if interested, to talk about your network and how
something like this might fit in.

Cheers,

Jawaid
