7. VoWiFi Handset
Test for Voice Access
1 Try to ping the PBX from a handset or a laptop.
2 Was the ping successfully echoed?
No: Check th
e PBX settings in the LAN as the problem is access to the PBX.
Yes:
If ping is successful from another client to the PBX, check the Voice settings (for
example PBX address) in the handset. This can be done from the PDM application or
the handset.
3 From the handset Device info m
enu or the PDM, check the following:
• The IP address of the handset is on the same subnet
as the IP-PBX or there is a
route to the IP-PBX in the network. Note that the value of the default gateway
must point to a route that can forward the package.
• That the IP-address of the IP-PBX is correct set
in the handset.
• That the supported VoIP protocol is selected.
• That the handset has an Endpoint number or Endpoint
ID that is registered in the
IP-PBX and if passwords are used for access to the IP-PBX, that it is correct.
4 Check that the APs maps VoIP packets to the Voice VLAN
if such are used. To do this,
access to the AP setup is needed, otherwise a “wired and wireless sniffing session”
must be carried out.
Test for Unite Access
A test for Unite access is, for example, to lo
gin to the Central Device Manager and see
if it is successful. Check that the hardware the Unite service is installed on is running
by performing the following steps:
1 Ping the Unite hardware from the handset or a laptop.
2 Was the ping successfully echoed?
No: ch
eck the IP settings of the Unite module.
Yes: check if othe
r handsets are listed as online in the Central Device Manager.
3 Check the Unite settings in the handset. The h
andset must have a User ID set.
Tip: Som
e of the Unite login parameters can be read from the Admin menu in the
handset but it is best to use the Device Manager in the PDM and Unite CM/IMS3.
4 Check the following parameters using the Devi
ce Manager in the PDM and Unite CM/
IMS3:
• The IP address to the Messaging gateway.
• If the correct password has been used at login.
7.1.4 Messaging or Voice Only
Messaging Only
A “Messaging only” message indicates that the ha
ndset is configured to use both Voice and
Messaging, but has lost contact with the PBX.
1 Perform the same checks for Voice problems described in section Test for Voice
Access on
page 53. Test for Voice access and then go to step 2.
2 Try to send a message. The idle connection ch
eck interval to the IMS3 is much longer
than to the gateway.
Note: So
metimes when all network connections are lost the handset will show
“Messaging only” for quite some time because it discovers it has lost connection to
the gateway much faster than it discovers loss of connection to the IMS3.
