Has anyone setup a Bogen with Callmanager Express? If so, did you use a FXO or FXS card to connect. Did you have to use a TAM B? Any help would be greatly appreciated.
I currently have it plugged into a FXO port with the other end connected to the TIP and RING. The speaker is then connected to 70V connection.
A loopstart Fxo trunk (default) should work.
They do say in this link that interface a telephone trunk to the amplifier requires a trunk interface adapter like TAMB.
