The English speaking hotlines are all using a pool system so regardless of which number you called, you would get a similar experience.
If you speak another language, call a number that speaks that language as you might connect faster.
Also, you could try calling at off-peak hours like US weekday mornings which would be EU/Doha noon/afternoon.
