T 38 Outbound Fax Problem (bearer capability not implemented (65) )

Hi all,

We don't have any issues with inbound fax transfer but when the client tries to send a document to an outbound number, right after the receiver hears the fax tone, the call drops. We use SIP trunk. We see the following debug messages :
