ATA 187 with fax, cannot do outside calls

Hi,

Can you help us with ATA187 fax issue?  Outgoing calls does not work. Ingoing calls work.

I have seen this document

https://supportforums.cisco.com/docs/DOC-25210

But I didnt find our call flow situation. Our call flow is

Telco - PRI - GW - H323 - CUCM - SIP - ATA187- Fax

What is the right configuration with this scenario?

Any help is appreciated.

CUCM Version

9.1.1.20000-5

John
