<p>Hello,<o:p></o:p></p>
<p>not familiar with python functions, have you tried with Kamailio transformation?<o:p></o:p></p>
<p><a href="https://www.kamailio.org/wiki/cookbooks/5.5.x/transformations#sdecodebase64url" target="_blank">https://www.kamailio.org/wiki/cookbooks/5.5.x/transformations#sdecodebase64url</a><o:p></o:p></p>
<p>Maybe you have to specify in Python that it is ASCII, I remember I had to do decoding when porting kamcli to work with Python3 -- had to change from using directly the variables received as parameter to a decoded value, something like:<o:p></o:p></p>
<p>prefix = tprefix.encode("ascii", "ignore").decode()<o:p></o:p></p>
<p>Also, if you can, share the identity header here to test with and see if can be reproduced.<o:p></o:p></p>
<p>Cheers,<br>
Daniel<o:p></o:p></p>
