System checks
Zone status
Go to Status > Zones on both Expressway-C and Expressway-E to check that the traversal zone is Active.
You can also check the zone status via Configuration > Zones > Zones.
If the traversal zone is not active:
n Review the traversal zone configuration.
n Confirm that the relevant ports are enabled for outbound routing on the NAT and firewall devices located
between the Expressway-C and Expressway-E (see Appendix 3: Firewall and NAT settings [p.42]).
n Confirm that the username and password credentials are configured correctly (and match) on Expressway-
C and Expressway-E traversal zones and in the authentication database on the Expressway-E.
Call signaling
If calls do not complete:
n Review the Expressway-C search rule configuration.
n Review the Expressway-E search rule configuration.
n Check the search history page for search attempts and failures (Status > Search history).
n Check the Event Log for call connection failure reasons (Status > Logs > Event Log).
