[asterisk-bugs] [JIRA] (ASTERISK-23329) Realtime Peers behind NAT becomes unreachable after peer reload

    [ https://issues.asterisk.org/jira/browse/ASTERISK-23329?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=215434#comment-215434 ] 

Michael L. Young commented on ASTERISK-23329:
---------------------------------------------

One thing that is probably not correct is that you have "directmedia" set to "yes".  You are working with NAT and that should be turned off.  If you do have that off for this peer, then it would probably be due to a bug that has been fixed in recent versions of Asterisk.

The other thing I would request is that you update to a newer version of Asterisk.  1.8.25 is the latest version and there have been some fixes in regards to realtime peers and NAT.

When upgrading, make sure you update your DB schemas since the schemas in the contrib directory were not up to date in 1.8.20.  They have been updated in recent versions.  Also, make sure you read the Changelog.  Upon updating, some of the default global settings in chan_sip were not being overridden and they will now be overridden properly if a peer is defining a different value from the default global values.

Please try the above and report back if this is still an issue for you.

Thanks

> I have a realtime peer behind NAT. Things work perfectly. I then did an asterisk reload, which caused the peer cache to be cleared, I then attempted to reach the peer. The private IP address from the Reg. Contact was copied over to the IP address, which caused the peer to be unreachable.
