[asterisk-users] Hold problem with Queue

[Elensarde]

Hello List,

First, sorry for my bad English skill, I'm French.

We have an asterisk 1.8.3.2 built from sources with a simple Queue :

[TestQueue]
strategy=ringall 					
timeout=15
retry=1
timeoutpriority=conf
ringinuse=yes
wrapuptime=2

member => SIP/002E31,0,Agent A
member => SIP/1CA3F2,0,Agent B
member => SIP/E08972,0,Agent C


And this dialplan (extension.ael) :

3600 => {
	Answer();
	Queue(TestQueue,,,,60);
	
	Playback(invalid);
	Hangup();
}


When somebody call this exten, an Agent take the call without problems.
But when he want hold this, phone try to hold the caller without success.
Finally, no signal in the caller-line and the agent-line is hangup
(for the phone), I not have errors or warnings in logs...

Any ideas ?

Thanks in advance, and kind regards,

Elensarde
