[Asterisk-Users] * Picks up line during outgoing call

[Matt Lawson]

We have some regular POTS phones connected to our incoming line as well 
as the machine that runs Asterisk.  Sometimes during an outgoing call 
from the POTS phone, the Asterisk will pick up also, and play its menu. 
 The FXO card is set to fxs_ks signalling; I'm told this might be the 
culprit but I really don't understand about the signalling types and 
what the ramifications of different ones are.

Any help?  Thx.
