>             Project: Asterisk
>          Issue Type: Improvement
>      Security Level: None
>          Components: Resources/res_pjsip, Resources/res_pjsip_refer

> h2. Off Nominal
> Because the remote attended transfer is similar to a SIP blind transfer, many of the off nominal scenarios are similar in nature.
> h3. No external_replaces extension
> * Alice sends an INVITE request, Asterisk sends an INVITE request to Bob
> * Bob sends a 200 OK to Asterisk, Asterisk sends a 200 OK to Alice
> * Alice sends a re-INVITE with restricted media to Asterisk, Asterisk starts playing music on hold to Bob
> * Alice sends an INVITE request directly to Charlie; Charlie sends a 200 OK directly to Alice
> * Alice sends a REFER request to Asterisk with a Replaces header that refers to the dialog between Alice and Charlie and a Refer-To header for Charlie
> * As the external_replaces extension is undefined, Asterisk sends a 404 to the REFER request
> * Alice and Bob continue to be bridged
