Sorry I am not familiar with the plans you outlined.
I use the Pay Per Call/minute plan which costs $1.95 per month plus $0.0198 per minute ... I am not sure if this per minute rate is for both outgoing and incoming ... regardless I have no issue with the rate since its far cheaper than what I was paying Primus.
I am far more concerned with Call Quality and reliability especially from incoming calls from my clients.--
