This link will bring you to Hydra channels. I have personally had success using it on my mobile phone as none of my many microphones owkr well with the laptop I use for vent. Here is a post I stole from Babab on Hydra forums on how to download and use the batphone system as intended.
Step 1: Download Discord on your phone and allow notifications.
Step 2: Download Discord on your computer.
Step 3: Watch for Batphone--It will look like this *BATPHONE* VS IS UP! MOVE TO KC 46+(will likely be spammed a couple of times)
Step 4: Turn on Roleplay
Step 5: Equip OT Hammer(don't hesitate...apologize do your groups(dont tell them what mob is up), and hammer as fast as you can)...(Yes you must have an OT hammer)
Step 6: Druids & Wizards will be waiting for you in OT to port/mobilize/SOW you.
Step 7: If you have a port class, log to them and mobilize others once you are set up.
Be prepared to watch someone else kill mobs that we target. That's to be expected as we experiment with batphone and getting quick forces together. Try and try again, and we will get mobs that we are looking for more and more frequently.
There will be no picking you up in another zone. Every single person needs to get an OT hammer and proc out. If you have a problem getting an OT hammer (1k from Yumaky or 2k on market), buy a WC cap( and keep it charged. WC and OT will be the ONLY zones that we pick up from for these raids. We need everyone's effort to be able to mobilize faster and make our porter's lives easier. These investments will mean a stronger raid force, and a stronger you.
