Fix SCN issues after upgrading to v5+ using Sonic Wall Firewalls. by hairlessupportmonkey
Posted: 11 Mar 10

Due to fundamental differences with the SCN in IPO v4.x to v5.x you will find your SCN might fail after the upgrade.

SSA and System Monitor will show the SCN is up and running, however calls across it will fail.

This is more than likely caused by H323 transformations.

This can be found under VoIP > Settings.


Un-tick this setting, and re-stablish the VPN, and if possible reboot one of your switches to re-initiate the SCN.

Calls should now route across the SCN as before the upgrade.
