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

I'm attaching a change which I believe will resolve this issue. Can you please apply it to your Asterisk, rebuild, test, and provide feedback? If it proves successful I will get it through code review.

> *NOTE*:
> The original issue was ASTERISK-24498. In that issue, Asterisk crashed when attempting to convert a received RTCP packet into JSON format. That crash is being fixed under ASTERISK-24498.
> After fixing the crash, the attended transfer being initiated by the SNOM was rejected with a 400 bad request. That problem is being handled under this issue.
> h3. Original Problem Description
> Asterisk crash trying to perform an attended transfer 
> ext 602 call ext 601
> ext 601 put the call on hold
> ext 601 call extension 603
> when ext 603 answers asterisk crashes
> Unattended transfer works properly
> If the attended transfer is made by the yealink phone (in other words echanging the roles of ext 601 and ext 602 above) it works properly
> Same scenario doesn't crash with asterisk 11.13.1
> I'm attaching log and backtrace
> h3. New Problem (REFER failure)
> {quote}
> I'm attaching the pcap capture for your further investigation.
> I tested the patch ... it doesn't crash anymore but the transfer doesn't complete in fact asterisk reply with a "400 Bad Request" to the REFER message from the snom phone. I'm attaching the log showing this, please let me know if you need the pcap.
