[Asterisk-Users] Attended Transfer failing with Agents

[Gavin Hamill]

using CVS HEAD :)  Some config snippets:

extensions.conf:
[from-ip]
exten => 51,1,Dial(SIP/1301,20,t)
exten => 52,1,Queue(ddi831,t)
exten => 53,1,Queue(marketing,t)

[internal]
exten => _13XX,1,Dial(SIP/${EXTEN},20,Tt)

queues.conf:
[ddi831]
strategy=roundrobin
timeout=10
announce-frequency=0
announce-holdtime=no
member => SIP/1301

[marketing]
strategy=roundrobin
timeout=10
announce-frequency=0
announce-holdtime=no
member => Agent/1600

qax*CLI> show agents
1600         (Smith.Suzanne) available at '1301 at internal' (musiconhold is 
'default')

qax*CLI> show features
Feature                   Default Current
-------                   ------- -------
Pickup                    *8      *8
Blind Transfer            #       #1
Attended Transfer                 *2
One Touch Monitor                 *1
Disconnect Call           *       *0

If I dial 51, the phone rings and atxfer works by *2
If I dial 52, the phone rings and atxfer works by *2
If I dial 53, the phone rings but hangs up the instant I press '*'.

Any suggestions would be warmly received, because 'set verbose 99' and 'set 
debug 99' print nothing whatsoever on this :/

Cheers,
Gavin.
