Play with the rxgain on your PSTN card. Increase it by 2 until it works. If it doesn't work, try decreasing by 2 until it works. If it still doesn't work then start playing with txgain (I've seen txgain changes fix DTMF issues, don't know why) -- Consulting for Asterisk, Polycom, Sangoma, Digium, Cisco, LAN, WAN, QoS, T-1, PRI, Frame Relay, Linux, and network design.
