How to identify port number used to outbound call (transfer call)?

I know $RV_PORTNUMBER identify called port but what with second one?

The RV is:

 

$RV[Conf_LineNbr_2]

 

The various $RVs created can be seen in the vgEngine trace.

 

The other RVs created are:

 

$RV[Conf_LineId_2]

$RV[Conf_Devname_2]

 

 

and these RVs hold information on the line that initiated the transfer:

 

$RV[Conf_LineNbr_1]

$RV[Conf_LineId_1]

$RV[Conf_Devname_1]
