Rusty Newton commented on ASTERISK-24664:
-----------------------------------------

It appears res_pjsip will allow you to configure an endpoint ID as such:

{noformat}
 Endpoint:  6001                                                 Unavailable   0 of inf
     InAuth:  6001/6001
        Aor:  6001                                               1

 Endpoint:  ΟΠΡΣΤΥΦ                                       Unavailable   0 of inf
     InAuth:  ΟΠΡΣΤΥΦ/ΟΠΡΣΤΥΦ
        Aor:  ΟΠΡΣΤΥΦ                                     1
{noformat}

However I get the same results with registration. Asterisk ignores the request and produces the error:

{noformat}

{noformat}

Asterisk does not respond to the request.

If we are can't handle these characters on requests, we shouldn't allow a user to configure objects using them. If we can't handle the requests, I wonder if a 488 Not Acceptable would be appropriate?
