-------------------------------------------

We have experienced the same issue.  I'm asking one of our engineers to attach a full log to this case.

>          Components: Channels/chan_sip/General

> Consider the flow as in http://www.in2eps.com/fo-sip/tk-fo-sip-service-05.html. Carol is the asterisk server in this case, Alice and Bob 2 (external) sip phones (i.e. NOT registered with asterisk). Asterisk acts for example as an application server. Bob wants to attended transfer Alice to this application.
> When Bob refers Alice to Carol (asterisk), Carol (asterisk) correctly accepts the invite, and masquerades the channels into the new Invited channel.
> The original channel to Bob becomes a Zombie, which is Hangup (see logging), but Asterisk fails to send out the BYE to Bob (message 22 in http://www.in2eps.com/fo-sip/tk-fo-sip-service-05.html#fig22).
> This result in Bob assuming the transfer is not complete yet, and keeping the call as "on hold" on his phone.
> Any thought on this issue?
