[Asterisk-Users] vars for transfered calls

[Jer]

Hi


when i try and transfer a call to another party
the setvars I have placed in sip.conf do not get passed to my dialplan at all
is there a work around for this so I can use them in my dialplan

but when i place a normal outbound call from that device the vars get 
passwd fine
I am passing an areacode - used by dial() and a cellnum used to forward the 
call when it is not answered

can someone help

Thanks

Jer
