Re: [reSIProcate] Stack Method or API to modify Via header by Application

[Alok Tiwari <alok1984@xxxxxxxxx>]

We do handover the sip message to sip stack through function send(sipMessage*). After that sip stack sends the message internally. In my case, if I modify the public IP in "Sent-by" parameter before handover the message to sip stack, it fails the message during Via header validation.

Use outbound decorators if you want to rewrite to public IP:
