asterisk users - Aug 2005 - Unable to transfer external calls to MeetMeconference (re-post)

This message was just bounced back to me.  I am not sure if it made
it to the list originally or not, as I received no responses. 

Since this message was written, I have installed Zap hardware into
this server.  The Zap channels can be transferred to the Meetme
conference.  The IAX2 calls still cannot.  

Any suggestions will be greatly appreciated.

		Sincerely,
		Trevor Hammonds
