[Freeswitch-users] doing an att_xfer from within a uuid_standby session (mod_callcenter)

Hi, I am trying to make an att_xfer from api. con.execute('att_xfer','sofia/gateway/provider/%s' % dstNumber, uuid) all is working, except when agent presses feature key 0 to bridge both parties, his uuid_standby call hangs-up too and so he is out of the queue and needs to log in again. Is there any solution to this problem? Thanks in advance. Khalil
