[asterisk-bugs] [JIRA] (ASTERISK-25171) Early completion of feature code attended transfer results in intermittent one-way audio, "ghost ringing" and robotic sound for some phones and not others.

Rusty Newton updated ASTERISK-25171:
------------------------------------

    Description: 
Three phones, A, B and C. 

A and B are Digium D40's. I've tested with C being an ATCOM AT-610PR or a Yealink SIP-T28P. If I swap C out with a Digium D40 the problem does not occur. It only occurs with the Yealink and ATCOM as C, and possibly with other phones that I don't have on my desk.

REPRODUCTION:

* A calls B
* A initiates feature code attended transfer and dials C
* While C is ringing, A hangs up. "blonde transfer"
* C answers and is bridged with B.

The result is that B, hears muffled and static-ridden ringing that goes on seemingly forever. Typically B does not receive audio from C, but every few calls B will be able to hear C. The received audio when available will be quite robotic sounding.

The audio from B to C is fine. C can hear B clearly.

Debug to be attached shortly.
