The Call Flow is such that a T38 Fax from a Softphone behind firewall is
sent through OpenPBX and to a SBC as follows

T38 Softphone -->Private LAN behind NAT-->Public LAN-----Internet----->
OpenPBX----->SBC --> Media Gateway--->PSTN


The call get sets up G729 and the SBC then RE-INVITES back to the
OpenPBX with T38. 

Will the above scenario work with Open PBX?

I know Asterisk had problems with a REINVITE and NAT. 

Can someone confirm?

Subject: [Openpbx-users] T.38 Passthru to Cisco 2811 CCM Expess?

I'm trying a work around by passing T.38 thru OpenPBX to a Cisco 2811
CCME/K9 to be terminated in a T1-PRI.

Do I need the Cisco Call Manager (express) to do this or will the
Advanced IP OS perfrom without CCE involved?
