Cannot receive Fax from PSTN on RightFax

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

Re: Cannot receive Fax from PSTN on RightFax

My dial-peer has some more entries :-) :

dial-peer voice 20 voip

preference 1

destination-pattern ...

modem passthrough nse codec g711ulaw

voice-class codec 1

voice-class h323 1

session target ipv4:XXX.XXX.XXX.XXX

incoming called-number .

dtmf-relay h245-alphanumeric

fax rate disable

ip qos dscp cs7 media

no vad

Maybe the Fax rate disable makes the difference.

Have a try

Maybe this sheet will help you:

http://www.cisco.com/en/US/docs/voice_ip_comm/uc_system/UC5.0.1/ipt_system_arch/COL_FMT.html

Use the Configuration File Portion for Originating Gateway and stick to dial-peer voice 5 voip

Re: Cannot receive Fax from PSTN on RightFax

Thanks for your reply, but always have the same issue.

Here is, debug voice ccapi inout, and debug cch323 all.

I hope that will give more information about this problem.

Thanks

Re: Cannot receive Fax from PSTN on RightFax

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....

Re: Cannot receive Fax from PSTN on RightFax

But when I call from an IP phone( the Fax server is like an H323 GW), I can hear The fax tone, I think if there is a problem in the fax server configuration, I cannot reach the number associate with the RightFax user.
