Why am I using PRI? Easy. It's cheap--or at least I was able to make it cheap.

Several years ago Vitelity was selling SIP trunks to non-business entities for next to nothing. I'm paying $21/month for phone service with 6 DID's. Long distance and international calls are about a half a cent a minute. Instead of using analog adapters I spent about $30 or so on a used Cisco router and a T1 card for it. SIP service in to the router, out as a PRI. Works very, very well, especially now that I have fiber internet service at home.

And mc601, I'm looking for the VMS and VMI options for now so I can use 3rd party voicemail--at least until I acquire an Executone voicemail card or VXC. Which card would you recommend?
