14 Troubleshooting Centry
Centry is a network device. The following are tips for troubleshooting:
Power
- Ensure the power to your device is working and rated for 802.11af/at PoE specifications if
using PoE. Centry should only have one source of power other than a backup battery. If not using
PoE, then main power needs to fall into 12-24 Volts DC.
Ping Test
- This determines connectivity and the packet loss and latency time to and from your
destination and the quality of your network connection to Centry. If you receive no response and
power is confirmed, contact your network administrator. You can also ping from within the phone
towards your IP PBX to test that it can reach its IP PBX/SIP Gateway.
Network
– If you’re putting Centry on a network that restricts ports, then the following ports must be
open for Centry to communicate to its appropriate IP PBX/SIP Gateway:
1. IAX2/UDP outgoing to port 4569 on IP PBX/SIP Gateway (only needed if using IAX2 instead
of SIP on the accounts page).
2. SIP/UDP outgoing to port 5060 IP PBX/SIP Gateway.
3. RTP/UDP incoming from IP PBX/SIP Gateway to UDP ports 23456-23556 (configurable).
DHCP
- Centry is set up for DHCP by default. If you cannot determine the IP address of your Centry,
contact your network administrator.
Account
- Ensure your SIP account is set up correctly. Account username and password must
match the account credentials on your VoIP system. This is the most common mistake with setting
up SIP accounts.
Codec
- Ensure the codec settings on your VoIP system match the Centry codec settings.
Firewall
- Firewalls commonly block or partially block VoIP calls. Check with your network
administrator if you cannot communicate with your Centry from behind a firewall.
Note: If you do not have a DHCP server running, use a standard home/wireless router and plug your
speakerphone and laptop into the same router. Once you know the IP Address, you can browse to it
via a web browser.
