Depends on what you're yelling at them about and what you tell them. I've picked up the phone and had a NOC guy at a russian SP (can't remember which, Caravan I think) kill off a syn flood that was hitting us promptly, at like 1 AM their time.

In my experience, most phone calls cause the ISP to become immediately hostile. They find abuse report phone calls extremely threatening / scary / etc. and go into full shields-up mode. 9 out of 10 times the very first words out of their mouth is "talk to our lawyers". the remaining 1 out of 10 is "block it on your end".
Email tends to be non threatening. As useless as it tends to be, it is still generally better than calling.
the real cesspool is POC registries. i wish arin would start revoking allocations for entities with invalid POCs.
