Follow these steps to add Wavix as your SIP trunk provider:
In the Account Details section, enter the SIP trunk ID and password that you set up for the SIP trunk on the Wavix platform
Enter your default Caller ID into the Main Trunk Number field. The Caller ID should be an active or verified phone number from your Wavix account.
In the Server Details section, enter the address of one of Wavix’s regional SIP proxies in the field labeled Registrar/Server.

Click on the Options tab and ensure that both inbound and outbound calls are allowed in the Configuration section.

Fig. 10 Wavix SIP trunk IP authentication
To activate the IP authentication on the Wavix platform:
Open the Wavix SIP trunk settings
Select IP Authentication in the Authentication method section
Enter your 3CX dedicated IP and click Submit
Click Save to apply the changes
IP authentication will be activated on your Wavix SIP trunk once the request is approved by the Wavix OPS team.
Important
After submitting the IP authentication request, you cannot update your IP address or change the authentication method. By default, an IP address can only be mapped to a single SIP trunk. If you need to have several Wavix SIP trunks sharing the same IP address, please contact support@wavix.com.
To place outbound calls you need to configure Outbound Rules. Follow these steps to configure your outbound rules:
Click on the Outbound Rules option in the left-hand side menu and click the Add button

- Selecting the DEFAULT group name
- Clicking OK
Scroll down to the Make outbound calls on section, select Wavix, and save the Outbound Rule

Fig. 12 Set route for an Outbound Rule
Note
All destination phone numbers must be in the E.164 international format. The E.164 format can handle numbers with up to 15 digits and is usually written as: [+][country code][subscriber number including area code]. Example: A US number in E.164 format would be +16561223344.
Note
Calls to numbers without a country code or carrying national access codes will be rejected by the Wavix platform
Below are typical examples of phone numbers incorrectly formatted according to the E.164 international standard:
Country

Number
6561223344
Reason

+16561223344
Country

Number
020 1122 3344
Reason
No country code, national access code with leading 0
Number in E.164 format
+442011223344
Country

Number
0041797000777
Reason
Leading 00 international prefix
Number in E.164 format
+41797000777
Table 1 International E.164 phone number presentation
Depending on your users’ dialing habits, you may want to strip leading digits or prepend a country code. For example, the below configuration can be used to prepend all dialed numbers with the leading 1 in case your users are accustomed to US domestic numbers in the national format.

When an inbound call reaches Wavix, it can be routed to your SIP trunk, a SIP URI, or a PSTN number.
Important
SIP trunks with IP authentication enabled cannot be used for inbound call routing as they do not maintain registration with Wavix SIP proxies. To configure inbound routing for your numbers you must specify a valid SIP URI address instead.
To configure inbound call routing to a valid SIP URI:
Log in to your Wavix account
Select My numbers under Numbers & trunks
Click on the three dots on the right-hand side and select Edit number. Double-click is also supported.
In the Transport drop-down menu, select SIP URI
Enter a valid SIP URI using the following format: +[did]@FQDN:port;transport=connection, where:
FQDN: fully qualified domain name or IP address of your 3CX instance
Port: SIP port used by the PBX
Connection: Could be either udp, tcp, or tls. The default transport is udp.
Click Add to add the destination for the DID
Click Save to apply settings
Note
The [did] parameter will be automatically updated with the actual dialed phone number when routing the call
You can also edit multiple numbers simultaneously. To do this, select multiple numbers you want to modify, then click on the Bulk actions button. The changes will apply to all selected numbers.
Make sure that all your Wavix numbers are listed under the DIDs tab of the 3CX SIP Trunk.

To test the SIP trunk place a call to your mobile phone number. Follow these steps:

If an outbound call fails check the following:
- You have completed all the steps in this guide
- The phone number you are dialing is in the international E.164 format
- The maximum call rate limit on your SIP trunk or account is enough to call the desired destination. You can check your effective rates in the My account section at app.wavix.com.
