Installing FAX with CCM

We are using CCM 3.0(11) centralized model and remote site has Cisco2620 voice G/W installing FXS interface for FAX and analog phone. This voice G/W on remote site are configured as H.323 device on CCM. And also the remote site has DT-24+ for PSTN call. All regions are using G.729.

There are no problems on voice call between FXS's phone and another device (IP Phone and PSTN phone). There are also no problems sending and receiving FAX to another region. But only we can not is sending and recieving FAX to PSTN side.

The following is the dial peer config on voice G/W on remote site:


dial-peer voice 602 voip

preference 1

destination-pattern +0T

voice-class h323 1

session target ipv4:

fax rate 9600

ip precedence 5

no vad


dial-peer voice 1234 pots

destination-pattern +1234

port 1/0/0


We confirmed that the FXS's FAX were able to call to PSTN FAX, and started negotiation. But FXS's FAX disconnect the call. We tried to send to another PSTN FAX from the other FXS's FAX. But we got same result...

What should we do?

Anybody know good ideas?
