[asterisk-users] Calls die when the answering party transfers

[Mohamed A. Gombolaty]

Dear All,

I am facing a strange problem that I can't find any matches for while
googling,  sometimes while a call initiated from asterisk to the PSTN is
answered and the answering party say the receiptionist tries to transfer
the call to someone else, the call dies, the full log shows nothing
useful and I am really unable to move forward on this issue, so can some
one suggest anything?

My zapata.conf is below also we are using Digium TDM400P with FXO
modules to connect to the PSTN.
