FXO BUSY --> Calls rejected with cause code 44

I have a next scenary:

 

PSTN --> E1 GW (2951) --> VG --> Phone analog.

 

 

The numbering published enters the PSTN to gw with a dial-peer sending it all to the VG, and is eg that by trunk-groups and dial-peers is what sends the llaamda ports associated with these trunks


When those ports associated this busy, the vg, gw returns to the network code 44 Cause i = 0x80AC - Requested circuit / channel not available

How could return to the PSTN, the user busy code?

I attached configurations, GW and Vg
