Hello,

have you already tried to use the default username format "1", the IETF format? 
This might be better for Kamailio.

If this solves the problem, the mode 0 should probably be removed then.

Cheers,

Henning

Subject: [SR-Users] Problem with auth_ephemeral and parse_uri(): bad port in uri

Hello,

I have a problem with Kamailio 5.4.6 and auth_ephemeral. I have the following 
in the Kamailio configuration

loadmodule "auth_ephemeral"
         modparam( "auth_ephemeral", "sha_algorithm", 3 )
         modparam( "auth_ephemeral", "username_format", 0 )
         modparam( "auth_ephemeral", "secret", 1234 )

as per

https://kamailio.org/docs/modules/4.1.x/modules/auth_ephemeral.html#auth_eph.p.username_format

and registrations fail. In the logs we see:

Jan  2 18:21:10 enswitch43 /sbin/kamailio[37501]: DEBUG: {1 545 REGISTER

Apparently Kamailio is confused by the timestamp following the username 
separated by the : character. The REGISTER message is below:

REGISTER sip:192.168.2.99 SIP/2.0

Allow: ACK,CANCEL,INVITE,MESSAGE,BYE,OPTIONS,INFO,NOTIFY,REFER
Supported: path, gruu, outbound
User-Agent: Raspberry Phone (SipJS - 0.11.6)

and Kamailio parses it as sip:<username>:<port> instead of 
sip:<username>:<timestamp>.

Is this a bug that should be reported or is there any setting that I am missing?
