>      Security Level: None
>          Components: Resources/res_pjsip_nat

> A routeset cannot be modified after the a SIP Dialog is created, thus the appearance of Record-Route headers in REINVITES is optional.
> res_pjsip_nat is designed to update the contact with received ip if there is no routset, and the topmost route header if there is a routset.  However if a re-invite omits adding Record-Route headers on a dialog that has a routset, res_pjsip_nat incorrectly updates the contact header causing subsequent messages asterisk sends to no be routed correctly.
