Hi, no one SIP device sends R-R, neither in initial INVITE or
re-INVITE. R-R (Record-Route) must be add just be proxies, and UAS
must copy them in the 1XX/2XX responses to the *initial* INVITE.
When creating an in-dialog request, the SIp device must insert Route
headers, no Record-Route.

I assume you mean that the *proxy* doesn't add R-R for in-dialog
request (the correct behaviour) so Asterisk fails and re-set the route
set.


Regards.
