Before I jump into Asterisk, I need to find if it’s suitable as a backup PBX to Televantage server we have. What I want is, if our current PBX, Veritcal Televantage server fails, I like to move T1 PRI from it to Asterisk box and we receive/make calls. Current set up is described below.
Vertical Televantage 7.5
Phone lines: 1 T1 PRI, 23 channels.
phones: Toshiba DKT-2010, DKT-2030
My plan. In case of the Televantage server fails, I unplug and plug the T1 PRI line(RJ45 connector) to T1 card in Asterisk box, then we make in/out calls through the box with the existing T1 line.
If then, maybe our current Toshiba phones will not work with Asterisk??? Is it possible to make Asterisk , somehow to convert the T1 PRI to SIP or VOIP so that we can make in/out calls using soft phones or Cisco VOIP phones? Or is there any already-in feature in Asterisk that supports various digital phones like ones we have?
I’m sorry to being vague, I can’t be much simpler than what I described here.
