I did but the workflow still says pending :( when I click on details it says I've already signed.

Thank you very much for finding this issue.

Unfortunately, we cannot skip the NULL terminator since it will make the printed result useless (and potentially dangerous), especially if the result is later passed to APIs such as pjsip_parse_*() or pjsua_verify_url() that expects the input to be NULL terminated.

For sip_tel_uri, it seems to be safe since endbuf has been decremented by one, so I apply the same approach to the others. I have created a new PR #3175 with the modified fix.
