Hello,
I do not think it is needed to remove the Via header for replication of
REGISTER. Is there a special purpose for it?
Cheers,
Daniel

Thanks Ohad, Samuel. t_replicate worked fine.
However, I faced one another problem.
If the Via header from UAC contains "rport" parameter,
then, removing Via header before calling t_replicate()
still adds the rport parameter with the value in the
newly added Via from Openser. Also, it doesn't add
"\r\n" to the new Via header, thereby, the next header
field concatanates with the Via header as below:
Here is the REGISTER received from openser using
t_replicate() function:

Note that Original "Via" is removed using remove_hf()
function before calling t_replicate. But, still
"rport" parameter is appended to the new "Via" header.
Also, the next header "Contact" is concatanated with
Via.
Please advice how to avoid "rport" being appended?
Thanks,
Vivek

You can also try to do it outside the config, using
the UNIX/FIFO

just my 2 cents..

Subject: [Users] Query on Registration
Hi,
I am trying to implement Third-Party
registration in
IMS environment using OPENSER as S-CSCF. Here is
what
I want to do:
UAC
........................................................................
..
...........S-CSCF
(Openser)
REGISTER
----------------------------------->
200 OK
<--------------------------------------
This part is working fine.
Now, S-CSCF sends separate REGISTER to
Application
Server (AS) and needs to get the response. But,
this
response should NOT be sent to UAC.
S-CSCF
........................................................................
..
.
AS
REGISTER
------------------------------------->
Response
([1-6]xx
<-----------------------------------------
I tried to send this REGISTER by removing old
headers
from the first REGISTER received from UAC and
creating my own (using remove_hf and append_hf).
Also,
I just removed the old "via" header, and Openser
automatically added new Via header with openser
ip
address.
However, when AS sends the response, S-CSCF
forwards
this response to UAC even though Via header does
NOT
contain the UAC IP address. Why is that? How
to
stop relaying the any response received from
AS to
UAC? Or else, is it possible to create a new
REGISTER
request from OpenSER?
Thanks,
Vivek
