====== Outbound Trunk Unavailable ======

Sometimes, with some firewalls, with IP routed trunks, the outbound trunk can become ''Unavailable''.  It seems this can happen after an Internet outage or trunk provider maintenance window. {{ :voice:pbx:freepbx:pjsip_trunk_advanced_settings.png?direct&350|FreePBX PJSIP Trunk Advanced Settings}}

Adjusting the PJSIP trunk advanced settings can definitely help.

May bring trunk back online immeddiately:

:!: Trunk name is ''vitel-outbound''.

<file>
/usr/sbin/asterisk -rx 'pjsip qualify vitel-outbound'
</file>

May save you a reboot:

<file>
/usr/sbin/asterisk -rx 'core reload'       # no down time
/usr/sbin/asterisk -rx 'core restart now'  # some down time
/usr/sbin/asterisk -rx "core restart when convenient" # safer
</file>

This one-liner can be used in cron to check the trunk status, restart Asterisk and notify you:

FIXME Not well tested

<file>
/usr/sbin/asterisk -rx "pjsip show endpoint vitel-outbound" | if grep -q Unvailable; then /usr/sbin/asterisk -rx "core restart when convenient" && echo "Detected Offline and Asterisk Restarted" | mail -s "XXXXXX Outbound Trunk" your@yourdomain.tld; fi
</file>
