Hi Grant,

Are you saying the Kamailio is failing to alter the URI or does the User Agent 
does something wrong?

Check the Kamailio log files if maybe the dialog module tracking does not work 
correctly here. Last year I did some work in this area, in my experience it 
should work ok also with the dialog module support.

If you can easily reproduce it, you can also do a test call in debugging mode, 
you will get more information about the uac logic in the log files.

Last thing - consider upgrading to a 5.2 or 5.3 based release, as 5.1 branch is 
end of life.

Cheers,

Henning

Subject: [SR-Users] uac_replace_from in 200 OK of BYE

Hello,

We've been using the uac_replace_from function to anonymize the From header to 
[email protected]<mailto:[email protected]>. The uac module 
makes use of the dialog module for restoring the original URI.
Everything works fine, except when the callee sends the BYE request (replaced 
uri is present in To header): the 200 OK received by the callee of the BYE 
suddenly contains the original URI in the To header.

We're running Kamailio 5.1.
Is this a known bug or limitation of the uac module?
Any way to have this replaced correctly (preferably automatically by uac 
module)?

Regards,

Grant
