SIP hairpin problem

Hello, i have a problem to make this scenario work:

PSTN call to phone whith CFA to another PSTN number. The call is not answer at all.

I use a 1760 gateway connected through a SIP Trunk to CUCM 5.1(2).

When i use H.323 connection, i have no problem. I think bri hairpin (call forward) with SIP is not supported.

What about your feelings ?

Thanks a lot !

Julien.
