Asterisk Team commented on ASTERISK-28876:
------------------------------------------

Thanks for creating a report! The issue has entered the triage process. That means the issue will wait in this status until a Bug Marshal has an opportunity to review the issue. Once the issue has been reviewed you will receive comments regarding the next steps towards resolution.

A good first step is for you to review the [Asterisk Issue Guidelines|https://wiki.asterisk.org/wiki/display/AST/Asterisk+Issue+Guidelines] if you haven't already. The guidelines detail what is expected from an Asterisk issue report.

Then, if you are submitting a patch, please review the [Patch Contribution Process|https://wiki.asterisk.org/wiki/display/AST/Patch+Contribution+Process].

Please note that once your issue enters an open state it has been accepted. As Asterisk is an open source project there is no guarantee or timeframe on when your issue will be looked into. If you need expedient resolution you will need to find and pay a suitable developer. Asking for an update on your issue will not yield any progress on it and will not result in a response. All updates are posted to the issue when they occur.

>          Issue Type: Bug
>      Security Level: None
>          Components: pjproject/pjsip
>    Affects Versions: 13.18.3
>         Environment: Linux 2.6.32-39-pve x86_64 x86_64 x86_64 GNU/Linux
>            Reporter: Serge
>            Severity: Critical
>
> When endpoints register via an edge proxy in front of Asterisk running PJSIP, the edge proxy adds a PATH header (https://www.rfc-editor.org/rfc/rfc3327.txt) so that Asterisk knows how to route out-of-dialog requests back to the proxy.
> When calling that endpoint, it appears though that INVITEs are sent to the Contact URI directly instead of being sent to the proxy with a preset Route header. Strangely, this happens only to INVITEs. Other requests such as the OPTIONS qualify initiated by Asterisk are sent correctly to the proxy with the proper Route header.
> When using chan_sip this problem does not occur.
> Asterisk certified/13.18-cert3
> PJ_VERSION : 2.7.2
> AOR/support_path : true
> Endpoint/rewrite_contact : false
> Endpoint/force_rport : false
