[asterisk-users] notransfer local channel on redirect

[Benko]

Hello!

On redirects(Got SIP response 302 "Moved Temporarily") calls are sent
to a local-channel in the sip-context. The billsec/duration is written
to the parent record. 
however, i would like it to write them to the record of the
local-channel. Is there a way to tell asterisk to add the
notransfer-option("\n") on redirected calls?

thanks
Christian
