[asterisk-bugs] [JIRA] (ASTERISK-30257) res_pjsip: IP addresses get butchered

[N A (JIRA)]

    [ https://issues.asterisk.org/jira/browse/ASTERISK-30257?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=260394#comment-260394 ] 

N A commented on ASTERISK-30257:
--------------------------------

I wasn't really expecting anything, just reporting it here in case there has been or will be a similar issue with more info.
The initial log messages about the bad packet have "56" and later on it is 556 so at some point somewhere, an extra 6 got added to that octet.
Unfortunately, this happened for a few minutes and then not again, but the packets in questions were from a SIP provider which is what had surprised me.
