How to make outgoing calls to different countries using different phone numbers?
If you want to make calls from different numbers to different countries, you can either create multiple SIP logins or use the "Identifying a number by call destination" feature of Zadarma's virtual PBX.
To configure this feature, go to the section My PBX - Outgoing Calls. In the "Destination" column, enter the country/city code you will be calling. In the "Displayed Caller ID" column, select the virtual number from the list that you want to appear as your caller ID.
The screenshot shows an example of rule settings where calls to Poland will be made using a Polish number, and calls to the UK will use a UK number. Calls to destinations not listed in this section will use the Caller ID assigned to the PBX extension.
