>          Issue Type: Bug
>      Security Level: None
>          Components: Resources/res_pjsip_rfc3326
>    Affects Versions: 13.21.1, 15.4.1
>         Environment: CentOS 7
>            Reporter: Ross Beer

> A lot of endpoints such as Cisco, Grandstream and Yealink have an issue with multiple 'Reason' headers.
> Removing the second Q.850 Reason header resolves the 'Answered Elsewhere' issue on all.
> It's not possible to remove the Q.850 header totally as this is used to pass hangup reasons between asterisk servers and other SIP services.
> Therefore a configurable option per endpoint would resolve this issue.
