Re: Uptime and Reliability - Utah business needs voice solution
said by forumsviewer:Yep. An Asterisk system can use TDM cards, which allows it to talk to regular voice circuits (POTS = plain old telephone service or PRI = primary rate interface, basically a digital T1). You can order fractional T1s and add channels as the business grows. The PRI channels wouldn't have to be incoming only, but for long distance it would cheaper to use VoIP for outgoing. You can even replicate this (on a small scale for home use) using an OBi110 or Linksys SPA3102 and a VoIP provider like CallCentric (assuming you have POTS service).
So basically the inbound phone numbers run through a different system or ciruit than the outbound? Meaning, outbound is 100% VOIP and inbound could be POTS or something else? Both inbound and outbound would be controlled by Asterisk (FreePBX)?
I guess I don't know what voice PRI (or POTS) circuit means and how that is different than SIP trunking.
SIP trunks are just the service you order from CallCentric or Anveo, or voip.ms, or whomever. The Asterisk switch talks to these via your Internet connection.
