[asterisk-bugs] [JIRA] (ASTERISK-24664) PJSIP Error processing packet on SIP requests with non-ascii characters in INVITE or REGISTER

[Joshua Colp (JIRA)]

    [ https://issues.asterisk.org/jira/browse/ASTERISK-24664?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=224925#comment-224925 ] 

Joshua Colp commented on ASTERISK-24664:
----------------------------------------

As it is this would require changes in pjproject to accomplish. The parser itself is considering it invalid, so it never reaches Asterisk itself thus it's not possible to send a response (even a 488).

> While investigating messages.log for my asterisk server; I found multiple occurrences of this pjsip exception (see attached log).
> It happens when the sip caller id is non-ascii, like this (first one appears in the log)

> This call is rejected from asterisk; and asterisk continues as normal.
> [Edit by Rusty - The call is *ignored* by Asterisk, with no response to the client. Asterisk produces an error type log message as below]
