Before placing or receiving a call, you need to have an active DID on your Wavix account. If you already have an active number on your Wavix account, the below steps are optional.
To purchase a DID on your Wavix account:
Log in to your account
Click on Buy under Numbers & trunks in the top menu
Select a country and region you wish to purchase a DID in
Choose a specific number or numbers and click Buy now button
You will be redirected to the Cart where you can confirm your choice and check out the DID(s).

Note:
Some DIDs may require a proof of local address and other documents before they can be activated. To enable these DIDs to receive inbound calls, upload the documents required, and wait until they are approved by the Wavix Number Provisioning team.
To create a new SIP trunk on the Wavix platform:
Select Trunks under Numbers & trunks in the top menu
Click the Create new button
Select Digest under Authentication method
Specify SIP trunk name, set SIP trunk password, and select one of the DIDs on your account as Caller ID
Optionally you can set max outbound call duration, max number of simultaneous calls via the SIP trunk and max call cost. If these parameters are not set, global account limits apply
Click Save

In the General tab in the Trunk Details section, adjust the name of the SIP trunk or update the field labeled Registrar/Server/Gateway Hostname or IP if needed. We recommend you to put the address of a regional Wavix SIP proxy located near to you in the field labeled Registrar/Server/Gateway Hostname or IP. The full list of the Wavix regional gateways can be found in the bottom of the page https://app.wavix.com/trunks. In the Authentication section provide SIP trunk ID and password set up for the SIP trunk on the Wavix platform.

Note:
By default, a new 3CX trunk supports up to 10 calls in parallel. However, for security reasons, all new Wavix accounts can place only 2 simultaneous calls. In case you’d like to adjust the limit, reach out to your account manager or email support@wavix.com
To save SIP trunk configuration click OK on the top of the page. It takes a moment or so for 3CX to register the SIP Trunk.
Click on Options tab and ensure that inbound and outbound calls are allowed and video calls are not in the Call options section.

Scroll the page down and check the Codec Priority. Wavix supports all the codecs listed below and G.711 is recommended for most cases.

In order to place outbound calls you need to configure Outbound Rules. Go to Outbound Rules in the left hand side menu and click the “Add” button.
Give your Outbound Rule a name and apply it to the Default extension group by:
Clicking on the Add button in the Apply this rule to these calls section
Selecting the DEFAULT group name
Clicking OK
Fig. 11 Assign an Outbound Rule to extension
Scroll to the Make outbound calls on section, select Wavix and save the Outbound Rule.
Fig. 12 Set route for an Outbound Rule
All destination phone numbers must be in the E.164 international format. E.164 numbers can have up to fifteen digits and are usually formatted as follows: [+][country code][subscriber number including area code]. An example of an US number in E.164 format is +16561223344. Calls to numbers without country code or carrying national access codes will be rejected by the Wavix platform.
Below are typical examples of incorrectly formatted phone numbers
Table 1 International E.164 phone number presentation
Depending on your users’ dialing habits, you may want to strip some of the leading digits or prepend the 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 number in the national format.

In order to receive inbound calls you need to configure Inbound Rules. Go to Inbound Rules in the left hand side menu and click on the Add DID Rule button.
Give your Inbound Rule a name, enter the number and set the extension to route calls to.

Click OK to save the rule. Depending on your business needs, you may set specific office hours for the rule and route calls to different extensions, voice mailbox or automatically drop the call based on the schedule.
For calls to be routed to your 3CX instance, log in to your Wavix account, select My DIDs under Numbers & trunk in the top menu, click on the three dots on the right hand side and select the Edit DID option.
