RR gave me a RCA router which wasn't working with VOIP router, so usadatanet credited me for SB5100 and telco is free of charge and i am paying $24.95 per month but with RR i would have to pay $39.99. and usadatanet have all features like caller id, forward, voicemail, call hunting etc etc. but with RR i don't even get Voice mail, i have to pay extra fee for that.
USADatanet is way much more economical for me
