Time zone: select your time zone for the sync with the external NTP server (NTP server section)
Sounds packages: select the sound packages to be installed
...
- Auto discover external IP address (Hardware, Virtual PBX): if enabled, uses DynDNS url specified below to discover the external IP
- DynDNS website url (Hardware, Virtual PBX): url of the service to discover the external IP
- External IP address (Hardware, Virtual PBX): external IP address manually set up
- External secure port (Hardware, Virtual PBX): (default 443): option to use a different port for TLS connections
Use only https (Hardware, Virtual PBX): If enabled, all http connections are redirected to the port 443 or the alternative https port (if configured)
Note Note: the parameter is enabled for Cloud PBXs by default.
- Random music on hold: if enabled, music on hold to be played back is selected randomly by the system
Default music on hold: select default music on hold
Note Note: Music on hold is selected using different Dialplan applications; in case this option is enabled, files present in the selected Music on hold directory of the Sounds menu, will be played in a random order.
- RTP start port / RTP end port (Hardware, Virtual PBX): set up the port range out of which the RTP ports are dynamically taken, normally 10 000 : 15 000
- Outgoing registration timeout (seconds): set up timeout for SIP registrations on the PBX, for stable connections it’s better to augment this value to reduce the network traffic
- Jitter buffer (min / average / max delay): set up the jitter buffer delay values
RTP / T.38 ToS / DSCP and SIP ToS / DSCP: optimal values are set up by default for these parameters and should be changed only if necessary
Note More information: How to set DSCP QoS for Wildix devices and Web Phone.
Important: after having changed DSCP value, to apply the changes in WMS network, it is necessary to restart WMS network in WMS Settings -> PBX -> WMS Network.
Use TLS / SRTP for local devices (Hardware, Virtual PBX) (WMS 4.0X):* TLS is by default ON for remote devices, here you can enable/disable TLS/SRTP encryption also for local devices
Note Note: The option is no longer supported in WMS 5.0X and will be deleted from the web the interface later.
All the devices (except GSM trunks W01GSM and DaySaver) connect now via TLS on VM/ HW PBXs (previously it was supported on Cloud PBXs). If you need to set another protocol, use custom provisioning parameter "SIPTransport".
- Auto add new devices in local networks (for 2 hours) (Hardware, Virtual PBX): when enabled, devices are added and provisioned automatically in local networks. After 2 hours the option is automatically disabled
Enable wideband codec usage for all networks: when enabled, codec priority is given to the wideband codecs of the remote devices
Note Codec priority is chosen automatically, normally the priority is given to the not compressed codec (G.711 aLaw) in LAN network and compressed (G.729) for remote connections.
- Enable wideband codec usage in LAN (Hardware, Virtual PBX):* enabled by default, the system uses G.711 codec in local network (IP classes specified in “Network field which must be considered local”)
- Networks where force usage of wideband codecs:* if the usage of wideband codec is disabled, it’s still possible to force its usage on some networks
- Custom Direct RTP Subnets: the networks that are considered local by the PBX and on which the wideband codec usage is forced
TLS Certificate (*.crt)(Hardware, Virtual PBX): upload a TLS certificate file
Note Generate certificate for SIP-RTP page on LINUX system:
- openssl genrsa -des3 -out server.key 2048
- openssl rsa -in server.key -out server.key
- openssl req -sha256 -new -key server.key -out server.csr -subj “/C=IT/ST=TN/L=My City/O=My Company/CN=examplecompany.com” (use your country instead of IT (Italy) and your region instead of TN (Trento))
- openssl x509 -req -sha256 -days 3650 -in server.csr -signkey server.key -out server.crt
Output: server.crt server.csr server.key
Upload server.crt and server.key to WMS Settings -> PBX -> SIP-RTP page.
This certificate serves for all types of connections, including SIP-TLS, HTTPs-TLS, XMPP-TLS.
LIMITATION: certificate should not be protected by password.
- TLS Private Key (*.key) (Hardware, Virtual PBX): upload a TLS private key file
...
S2S authentication via token for Wildix PBX API significantly increases security and protects your PBX from potential attackers. Documentation and instruction on how to generate the token and how to sign it with a secret key, is available on your PBXs: https://<pbx_host>/api/v1/doc/#tag/Authentication/bearer

- DMZ wtun0 (static) interface is used for connection to WMS Network. The interface cannot be edited unlike enth0 and enth1 interfaces
