[cisco-voip] ground start loop start

[Voll, Scott]

In our area the only way to get Ground start is to order it.  All POTS
PSTN lines are Loop start.  If you can use a regular analog phone, It's
loop start.  Ground start requires grounding of the line in order to get
dial tone and work.

 

Believe it or not, I had to order a Ground start to get disconnect
supervision to work.  It's a pain. I also found out it does matter if
the two wires are backwards.

 

Hope that helps.

 

Scott
