Cannot receive Fax from PSTN on RightFax

Question

here is our call flow, PSTN-> GW H323 -> RightFAX -> Exchange -> outlook
- We can send fax from outlook client to an external fax without any problem.
- We can send fax from rightFax to outlook.
- We can't receive fax from external fax, when we call the fax number associate with an outlook client, we hear a busy tone.
- I think that's a problem between H323 GW and RightFAX.
- When I configure the rightFax like a gateway H323(add route Pattern), and I call a
number associate with a user on rightFax, I can hear the Fax tone.
Can you tell Me how can I solve this Issue.
My T38 Config for H323 gateway
voice service voip
allow-connections h323 to h323
supplementary-service h450.12
fax protocol t38 ls-redundancy 0 hs-redundancy 0 fallback none
dial-peer voice 30 voip
destination-pattern 2130
session target ipv4:172.17.231.86 !@ IP of RightFax
dtmf-relay h245-alphanumeric
You'll fid enclosed the brouktrout configuration.
Need help.
Best regards

Answer 1

to be honest i have no idea then.
But in your logs i see:
18 16:47:55.138: //1866/5BE70897804F/CCAPI/cc_api_call_disconnect_done:
Disposition=0, Interface=0x466E185C, Tag=0x0, Call Id=1866,
Call Entry(Disconnect Cause=47, Voice Class Cause Code=0, Retry Count=0)
and Cisconnect cause 47 means: Resource Unavailable, Unspecified. This cause is used to report a resource unavailable event only when no other cause will apply.
Maybe you'd better to investigate your faxserver....
