International PSTN interconnect
[edit]Speaking of the global PSTN, I'd be fascinated to know how British telcos are going to interconnect with other countries which still perform international interconnection via circuit-switched links -- if there are any, that is; are international circuit-switched trunks still a thing, or is international interconnection all VoIP now?
I'm thinking of places like Bhutan, Chad, etc, which are generally late on the uptake of new technologies. Do they have large-scale VoIP gateways for this? Would it be, for example, cheaper for a UK telco to haul VoIP traffic to a nearny international PoP and present it to the local telco via a VoIP gateway there? Or do they do TDM-over-IP to these locations and have a UK-based VoIP gateway, and just a couple of routers and plug-in 1U Ethernet IP-to-TDM boxes at the far end? — The Anome (talk) 14:57, 4 October 2023 (UTC)
