Looking for reliable SIP provider (calls to US)

I'm looking for reliable SIP trunk provider for US calls with decent connection rate. Own semi-warm DB, manual dialing, no scam, no nuisance calls or anything similar.
But like with any not super warm DB we don't get those 120 sec+ ACDs and ASR might be not that great (but not awful).
Any suggestions/recommendations?

If you are doing manual dialing @mike_ph you probably want to steer clear of the strict tier 1s like twilio. they will hit you with surcharges or just suspend the account if your acd drops under 60 seconds too often. try looking at telnyx or maybe commio... telnyx is usually pretty tolerant with conversational traffic as long as you are not running automated scripts and keep the concurrent channels low. just make sure you get your stir/shaken profile sorted with whoever you use or your connection rate will tank anyway because of the carrier spam labels.
