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.
