Hi Walter,

If you click on "Gerrit Reviews" tab it has all gerrit reviews for this topic.

To manually manage/provisioning remote (behind the NAT) SIP devices it's necessary to know internal ip-address.
We could get internal ip-address using old-SIP AMI command 'SIPShowPeer'
For example
Reg-Contact : sip:user at 192.168.1.2:5060
Using PJSIP we couldn't because res_pjsip_nat rewrites contact's address before
AMI event is sent.
To find out internal ip-address 2 SIP headers can help: Via and Call-Id.

>          Issue Type: Improvement
>      Security Level: None
>          Components: Resources/res_pjsip, Resources/res_pjsip_registrar
>    Affects Versions: 13.9.0
>            Reporter: Alexei Gradinari
>            Severity: Minor
>
> As res_pjsip_nat rewrites contact's address, only the last Via header can contain the source address of registered endpoint.
> Also Call-Id header may contain the source address of registered endpoint.
> Added "via_addr", "via_port", "call_id" to contacts.
> Added new fields ViaAddress,CallID to AMI event ContactStatus.
