Express Talk is a very nice interface, and I'd like to use it with my Gizmo accounts, but I'm having some trouble. I can place a call through Express Talk and I can answer a call with Express Talk, but I can't hear any audio on either end. I went through the Audio Wizard successfully, and control information (like hold tones) work just fine, but I cannot hear any audio at all. I'm running Express Call on an XP laptop with an attached headset. My other Gizmo number is configured on an ATA (Sipura 1001) with a "hard phone." I can dial and ring the laptop from the phone and the phone from the laptop. Both systems act normally when I "answer" (that is, ringing stops, Express Call recognizes the caller and the fact that the "phone" is off hook, and the connection should begin, but it doesn't). The Express Call settings dialog doesn't seem to want anything exotic like a codec type, but I've tried both the higher and lower quality audio settings with no good result. The single-line Gizmo software works fine on this box. What should I try next? Thanks! --George
