Again, if it's important enough that you can't just call them back after the match than trials probably wouldn't matter at that point anyways. Seriously what's so important that you can't call back in like 5-10 minutes? Is someone going into labor? Well screw the trials than, did someone die? Screw trials than. Is someone in danger? There's a pattern here. Oh my mother is calling me. I'll let it go, if it's an emergency she'll call back. I'll call her back after. Oh my boss is calling me. Well I'm off the clock it's weird that they're calling me at all, I'll let it go to voicemail.
