Transfert with atxfer


please forgive me for my bad english, I’m a french pepople.

I’m running under asterisk 1.4.22 and I have a litle problem with atxfer. If I formward a call using the blindxfer, the callerid is the original one (the caller one). But if I user atxfer, the callerid is the same as the blindxfer (the caller one).

How could I add a flag to indicate to the final person that it is a transferee call ? If i can change the callerid with the callerid of the transferer, it’ll be nice.

[featuremap] blindxfer => ## atxfer => ** automon => *1

Thanks for your helps.
