asterisk users - Feb 2008 - Problems with Refered Call and Accountcode using siptapi

Hello,

I am having a problem with an call openend from the siptapi application 
(http://www.enum.at/SIP-TAPI.479.0.html) to a phone which is refered to 
another external number after the phone picks up. I see in the Sip 
Traffic that everything is fine with the exosip client used in siptapi 
and the phone. There is the right accountcode and everything runs fine.
When i pick up the phone, the siptapi app. sends a REFER Msg to transfer 
the call to another external number (selected in outlook or any other 
Tapi Application). The Problem is that there is no ACCOUNTCODE after the 
Refer.
I?ve set the accountcode with Set(cdr(accountcode)=${ACCOUNTCODE}) 
before the dial cmd to the phone.

Could it be a problem that the sip communication is from and to the same 
user? This is to identifie the right phone to call.

log from the refer sip msg:

here the Var ACCUSER and CDR(accountcode) should be set with the 
${ACCOUNTCODE} which is empty.

I hope someone could see an error i havent found.
