[Freeswitch-users] Cannot Blind Transfer 1 Legged calls

[assgeo8 at gmail.com]

Hi,

I've be trying to get the attended transfers to work without success.
Freeswitch setup is 1.2-stable with the default configuration. I have 3 
yealink phones 1001-1002-1003.
I call from 1001 to 1002 - OK
I initiate the attended transfer from 1002 to 1003 - OK (it's just like 
another call & 1001 gets moh)
Then I transfer 1001 to 1003 but it fails, returning the call to 1002 
with the message 'transfer failed"
Looking at the logs i found this error : Cannot Blind Transfer 1 Legged 
calls prior to Processing Extension 1001 <1001>->1003 in context public
Why this error? Maybe it's because the processing goes to context public?

Regards,

Jeff
