Don't know much about VOIP. Can someone reccommend an ATA that I can plug in one analog telephone that will allow me to dial and receive calls on: one POTS landline phone number; and 2 IP phone accounts. One of the IP phone accounts is from my cable ISP, and the other is one of the internet SIP phones called Stanaphone. I recently bought a Sipura SPA3000 to configure like this, but from what I understand on this unit you can only configure a total of two accounts including the POTS line.
Thanks for any help.
