Choosing phone numbers to use with Pexip's BYOC
To use Pexip's "Bring your own carrier" (BYOC) you need to decide which phone numbers to purchase from your chosen telephony carrier and which prefixes you want to associate with those phone numbers.
For more information about prefixes, see Defining prefixes to use with Pexip's BYOC or for an introduction to BYOC, see Pexip's "Bring your own carrier" — using your VTC system to dial out to PSTN.
You may only need one phone number to achieve all the calls you want to make. However, with a single Pexip BYOC license you can have as many phone numbers as you need. You may want to buy more than one number if your organization makes a lot of calls to PSTN destinations in certain countries/regions. By purchasing phone numbers in the same country/region as your call recipients, you may be able to reduce costs. It also means your PSTN call recipients see a same-country/same-region phone number on their caller display.
The examples below show different scenarios using one or more source phone numbers.
Please note that each source phone number needs to have a rule configured within Pexip using a unique prefix value. The video endpoint user enters the prefix so that the service can apply the correct rule and source phone number to use for the call.
The examples below show what happens in different scenarios when an organization places a call to a PSTN destination.
This example shows calls being placed to different cities within the UK (London, Cardiff and Glasgow) using the same UK source phone number.
This example shows calls being placed using the same UK phone number to call recipients in different countries: the UK, the US and Australia. All call recipients' caller displays show the same source phone number, so the American and Australian call recipients see an international incoming call.
In this example an organization has bought three phone numbers: one UK number, one US number, and one Australian number. Call recipients see a phone number in the same country as them.
