Subtractive EQ first for me, too. I'll throw a Q10 on there and find the first, most obvious ringing tone, and go -18dB with the smallest Q setting. Then find the next ringing tone, and repeat. It's not uncommon for me to get rid of more than 10 of these little ringing tones. Usually some of them I will reduce only -5db or so though...only -18dB when they're super obvious. From there it's normally just a little bit of broad reduction in the low mids, and sometimes some more focused reduction in the 2k-8k range to get rid of some of that overpowering hissiness that comes out especially when compression is applied. As for the reverb, I'll normally roll off around 11k as I feel like that super high stuff makes the reverb sound fake.
