[Asterisk-Users] IAX2->SIP->meetme = ZOMBIE

[Ryan Courtnage]

If someone has both IAX and SIP clients, would you please attempt to
duplicate the below problem?  I don't want to submit a bug unless the
problem can be verified.

The SIP client must support attended transfers (ie: sayson, uniden):

1) Make a call from an IAX extension to a SIP extension
2) On the SIP phone, use attended transfer (not #) to transfer the call
to a meetme room  
3) Execute 'show channels' at the * CLI

Do you see any 'zombie channels'?

Thanks in advance,
Ryan
