Re: [reSIProcate] Route Set problem with Update in resip 1.1 RC1

This is interesting. I do not think it would be correct to change the Record-Route stack to reflect the Route set in the dialog. Obviously something in the middle is confused if this happens, and changing the Record-Route stack in the response is liable to confuse it even further. Both endpoints should just ignore the Record-Route header-field-values entirely, I think.

Any other opinions?

Best regards,
Byron Campen
 
There seems to be another problem with Record Route processing.
 
After an established dialog, an Update is received that runs through Helper::makeResponse() to build a 200 msg that does not contain the correct Route Set.
 
I had found this error in a different scenario, i.e. a response, which is fixed. Now I see this in an Update, i.e. a request.
 
I believe the problem is at Helper.cxx line 410
 
Here's a log snip, correct route set in ACK in blue, bad route set in 200 OK in red for same call-id:
