Hi Leonid,
what do you mean by "removes"?. When sequential requests are processed,
the Route header corresponding to your server will be completely
removed.

Hi,
I see that when Openser 1.1 receives re-INVITE it removes parameter
"did=" from header field Route before sending it to the second call
party.
Any idea?
Thank you in advance,
Leonid

New subject: [Users] Problem with dialog module
Hi Leonid,
you should not do RR for the sequential request. According to RFC3261,
the routing set is established by the initial request (formed by RR set
+ contact) and it does not change across the dialog lifetime.
The clients should ignore any RR from the sequential requests (like
re-INVITEs) and to keep using the RR set form the original INVITE.
regards,
bogdan

Hi Leonid,
what do you mean by "removes"?. When sequential requests are processed,
the Route header corresponding to your server will be completely
removed.

Hi,
I see that when Openser 1.1 receives re-INVITE it removes parameter
"did=" from header field Route before sending it to the second call
party.
Any idea?
Thank you in advance,
Leonid

New subject: [Users] Problem with dialog module
Hi Bogdan,
Thank you very much. I changed the configuration script in such a way
that record_route() is called in the "else" branch of loose_route()
test. It fixed the problem.
Best regards,
Leonid

Hi Leonid,
you should not do RR for the sequential request. According to RFC3261,
the routing set is established by the initial request (formed by RR set
+ contact) and it does not change across the dialog lifetime.
The clients should ignore any RR from the sequential requests (like
re-INVITEs) and to keep using the RR set form the original INVITE.
regards,
bogdan

Hi Leonid,
what do you mean by "removes"?. When sequential requests are
processed,
the Route header corresponding to your server will be
completely
removed.
regards,
bogdan

Hi,
I see that when Openser 1.1 receives re-INVITE it removes parameter
"did=" from header field Route before sending it to the second call
party.
Any idea?
Thank you in advance,
Leonid
