I am in the process of evaluating if I should use Asterisk. Does Asterisk require a media card to support 3 way conference or does it do media processing by software? Does Asterick support CTI standard such as CSTA to control calls in a TDM PBX? I read it somewhere that Asterisk supports Intel/Dialogic CT Connect card. Has anyone used that before? Does it need a CT COnnect card for the CTI link separate from the FXO connection card? or does that one card does both? Please help. Thanks.
Asterisk does not require additional hardware for 3 way calling. It does not support CSTA. Take a look at the links below for info on Asterisk support for Dialogic cards.
Thanks you very much for the info. It is great that Asterisk does 3WC without external media card. On the CTI interface, I am not looking for a CTI interface to control Asterisk, instead I am looking for a way to control another legacy PBX from Asterisk using a CTI interface. Are you aware of any legacy PBX CTI control card that can be controlled by Asterisk?
