Record with bayonne 1.2.15

Hi,

I write because I have some troubles with the record command in ccscript.

I need to record conversation that customers have with our technical 
support.

I use dialogic cards ( D120JCT and D41E to do outgoing calls to the 
technical support and incoming calls are taken on a D300 PCI ).
The join works like a charm but with the command wait timeout=10s 
record="/path/to/myfile" I only record the technical support answer but 
can't record the customer voice.

I tried with join record="afile" but nothing happens.

Searched the manual but don't found anything relevant.

Has someone an idea please on how to do it or is it impossible ?

The point is that it was working flawless with the same hardware with an 
other IVR soft ( GAP for those who heard about it ), but GAP is not as 
good as bayonne for my production needs.

Thanks in advance for help !

Cheers
