Andre Luis commented on ASTERISK-21787:
---------------------------------------

After trying to setup the OS again, reinstall asterisk 11.4.0 and just add the accounts to the iax.conf everything rest as default, one thing happens
first time the asterisk servers comes up on both servers, the IAX2 communication works 100% perfect, if I stop Server 1, server 2 recognize peers as UNREACHABLE
after a few seconds(10), start server 1 again(asterisk process i mean), server 2 -> server 1 back to REACHABLE, but on server 1 starts as REACHABLE and a few seconds later(3 sec)
changes to UNREACHABLE.

Still strange behavior!

> When setting communication between two asterisk servers using IAX2 either user/peer or friend accounts there is no communication,
> peers always unreachable from the startup, this affects versions 11.1.0 thru 11.3.0,
> when using 11.0.2 or below works fine.
> The configuration files, debug information and tcpdump form each server is attached.
