[BUG] Can't pick up phone / stuck in a call

[crossroach]

Note - this is a fresh game created on 1.5

I'm expecting two calls on my save, one from River (to invite me over) and one from Regina (finished all psychos). When either calls me i'm unable to pick up the phone by pressing T, i'm also unable to reject it by holding T. However after they hang up, i'm still stuck in the call and all it's restrictions, ie can't fast travel, talk to people or sleep, however i can still open up the phone directory and even initiate a call (even though that does nothing other than ring a couple of times). This pretty much means i'm stuck, since getting the call is inevitable, and all story missions rely on talking with characters which i can't initiate.

I remember this bug from way back, and at the time the fix was to force another call, as in this could be fixed by getting close to a gig in order to get the fixer to call you, terminating the previous call you were stuck with. However this doesn't work in 1.5. The toggle they added which makes fixers send a text instead of calling you altered the default behaviour. Even if you have the calls turned on, if you're on the phone at the time the fixer would call you, they send a text instead.

Does anyone know of a new solution for 1.5?

EDIT: For posterity, things i tried
verify game files - no change
force a call from fixer - they send texts when on call now
start combat - before initiating combat i'm able to open the phone menu, after combat ends it turns red as it would if you were on call
reload previous save - could be i haven't noticed this bug, even the oldest save has this problem
wait 24-72 hours for another call - never comes
completing a random gig - no change

I continued to run around, did two gigs without change. For some reason i walked past delamain HQ (I have the Epistrophy quest on 'Return to Delamain HQ' step). As soon as i moved to the entrance door, all the calls i made/would have received went through (about 6 were queued, played one after another), and now my phone is working as expected again.

Whatever this bug is, it's connected to the Delamain questline.
