Hi If I have a inbound call frompstn which hits SER, and then the call is passed to asterisk, the receiver then decides to transfer the call, can this be controlled within asterisk/ser, without the PSTN gateway being involved, I was thiking that although REFER messages are sent, couldnt SER take care of this and just transfer the call to a new sip contact. The problem I have got is that I have a upstream gateway which doesnt support REFER :-) Iqbal
