A pair of smart modems should certainly be able to connect, but it's very likely they would only be able to negotiate a fairly low speed. The classic 300 baud Bell 103 modulation can probably work perfectly fine even over early 2010s Skype. Although possibly with a lot of dropped bits...

I remember dialing into a BBS in the mid 2010s over an international phone call going through a late-stage digital switch locally (possibly one of the later AXE switches but I have no way of knowing for sure anymore), and the call would almost have to have gone through lossy compression on its way to the US.

300 baud will not work. arp/tcp/ip have too much overhead even with small MTU.

slip/plip/ppp is workable from 1200 baud up.
