SCN Line not trunking calls after 5_0_24 upgrade

[CamIAm]

I'm attempting an upgrade to version 5.0.24, on two 406v2 control units, which share a centralized VMPro. After upgrading both control units, the SCN line at the main site stops trunking to the satellite office. Any other installed H323 lines at either site work normally, after the upgrade.

When the remote site is downgraded to 4.14 the SCN returns to normal functioning. I've performed this upgrade at two of our offices, without having any issues.

Thanks for any suggestions.

Have you tried deleting and rebuilding the SCN line after the upgrade?

THis may be a route/firewall issue. R5 introduced something that causes SCN trunks to get screwed up by the firewalls. If using Cisco make sure Fixups/inspects are off. Sonic wall H323 transformations off and Juniper make sure H323 is unchecked under alg

Thanks for your posts.

I have tried re-creating the SCN lines, using different line numbers, without any change. It might be the firewall(s)I will check into that.
