I briefly did customer support like this, the bigcorps have various call centers many of which are other companies outsourcing it (I was and am in the US although obviously offshore exists too). I don't think there is a technical limitation, it is just a decision both companies make on the cost/benefit of having to come up with some protocol and integrate/require that with every 3rd party call center.

There were Tier 1's people talk to, no idea where they are and I was WFH taking escalations and asking same questions again.
