<p>Hello,</p>
<p>not familiar with python functions, have you tried with Kamailio
transformation?</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></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:</p>
<p>prefix = tprefix.encode("ascii", "ignore").decode()</p>
<p>Also, if you can, share the identity header here to test with and
see if can be reproduced.<br>
</p>
<p>Cheers,<br>
Daniel<br>
