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 in Configuration > Zones > Zones.
also check the zone status in Configuration > Zones > Zones.
If the traversal zone is not active, do the following:
■
Review the traversal zone configuration.
■
Check that the relevant ports are enabled for outbound routing on the NAT and firewall devices located
between the Expressway-C and Expressway-E. See
between the Expressway-C and Expressway-E. See

■
Check 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.
and Expressway-E traversal zones and in the authentication database on the Expressway-E.
Registration Status
Check that all endpoints which are expected to be registered are actually registered to the relevant Expressway. And
that they are registering the expected aliases. All successfully registered endpoints are listed on Status >
Registrations > By device.
that they are registering the expected aliases. All successfully registered endpoints are listed on Status >
Registrations > By device.
If the expected endpoints are not registered, review the following items:
■
The endpoint’s registration configuration.
■
The SIP domains (

).
In some cases, home endpoints may fail to register when using SRV records. This can happen if the endpoint uses the
home router for its DNS server, and the router's DNS server software doesn't support SRV records lookup. (Also
applies to the DNS server being used by a PC when Jabber Video is running on it.) If registration failure occurs, do
either of the following:

applies to the DNS server being used by a PC when Jabber Video is running on it.) If registration failure occurs, do
either of the following:
■
Change the DNS server on the endpoint to use a publicly available DNS server which can resolve SRV record
lookups. For example,

Google – 8.8.8.8
■
Change the SIP server address on the endpoint to use the FQDN of a node in the Expressway cluster and not
the cluster SRV record. So that the device performs an AAAA or A record lookup.

Call Signaling
If calls do not complete:
■
Review the Expressway-C search rule configuration.
■
Review the Expressway-E search rule configuration.
■
Check the search history page for search attempts and failures (Status > Search history).
■
Check the Event Log for call connection failure reasons (Status > Logs > Event Log).
