Which call u need to forward ? calls from SITE A to site B if not answered will get forwarded to PSTN using FXO or if  someone call Site B from PSTN and if not answered you need to forwarded using the Same Site B FXO to PSTN.

Yep, i want calls from SITE A to site B if not answered will get forwarded to PSTN using FXO. i think because analogphone connected to Cube by fxs port so i cant conffig ephone.

thanks

I hope you are using dialpeer for FXs port. 

AFAIK it will be possible if the analogue port is configured as ephone. With dialpeer it’s not possible.

Try to register the fxs  port as sccp device using  stcapp and apply the configuration @Roger Kallberg mentioned.
