No Fax Tone :(

[mrmhar1408]

PSTN -(SIP Trunks)->VGW3845 -(SIP dial-peer)-> CUCM 8.0 --> Unity call handler --> CUCM route pattern -SIP Trunk-> same VGW3845 --> fax server.

once the user dial the fax extension i can't hear the fax tone however if i forward the call from the VGW directly to fax server i can hear the fax tone.

attached my router config.

Why is your call to the Fax server going through the Unity Call Handler? Also, what do you mean "

if i forward the call from the VGW directly to fax server i can hear the fax tone."

When you dial the no. to reach the fax server what happens? does the call drop immediatly?
