Pexip's "Bring your own carrier" — using Pexip to dial out to PSTN
Pexip's "Bring your own carrier" (BYOC) enables users to dial out from a Pexip-registered video endpoint to PSTN numbers such as landline phones, mobile phones and audio bridges. So organizations no longer need a separate telephone in conference rooms.
The customer selects and engages a telephony carrier, and provides implementation details to their partner who then creates the necessary configuration. When a call is placed the Pexip Service routes it out to the chosen carrier who then handles the call the rest of the way.
BYOC currently supports calling from video endpoints registered to the Pexip Service only (it does not currently support calling from Trusted devices or the Pexip apps.)
Here's an overview of how it works
BYOC is flexible, and gives the customer control over which carrier to engage and the call plans they want to have. Here’s an outline of the things a customer needs to do to get BYOC up and running.
- First, the customer decides which calls they want to make and which carrier they want to deliver the calls.
- They can have more than one carrier if they want.
- Pexip currently supports Twilio, Unifon (Norway only) and Voxbone but other carriers can be onboarded and tested on a case-by-case basis.
- The customer manages the commercial relationship with the carrier directly. So they can agree the call plan, routing options, and toll charges for the call segment handled by the carrier. Some customers already have an existing carrier. In these cases, they can simply continue their set-up and enable BYOC on Pexip for this carrier.
- They can use their own Session Border Control, if required. There are no technical limitations that prevent it, but it needs to be configured and tested.
- They obtain a BYOC license from their partner and this enables the feature for all their video endpoints.
- ERC premium customers pay no additional cost.
- Otherwise the cost is based on the number of video endpoints they have registered to the Pexip Service.
- They provide implementation details to their partner, who completes the configuration in the Partner Portal:
- Proxies define the carrier SIP addresses that allow Pexip to deliver the call to the carrier.
- Routing rules are configured based on the customer's and carrier's requirements, and rules also determine what the user enters at the video endpoint when placing calls.
To understand more about what's possible within the configuration and the implementation details that the customer needs to provide to you, see Configuring BYOC.
If the customer requests a different carrier or wants their own Session Border Control please contact your Pexip Solution Architect.
Here we help partners:
- Understand the options available to the customer for organizing rules depending on how many caller-ids they have with a carrier and what they want their users to enter when placing calls.
- Complete the configuration in the Partner Portal.
Here are the steps required to configure BYOC in the Partner Portal.
- Order a BYOC license. For help ordering licenses see Ordering a new license plan.
Complete BYOC configuration in the Partner Portal:
- Configure a proxy for each carrier the customer wants to use.
- Configure rules for different types of calls.
To find the BYOC configuration screen, go to the company you want to configure and select thetab.
First, you need to configure a separate proxy for each carrier to be used by the customer, they can have one or more carriers for BYOC. The proxy holds the information that the Pexip Service needs to route the call to the carrier and authenticate with the carrier. The customer provides you with this information as they work with their chosen carrier directly.
Rules enable the Pexip Service to route calls to the correct carrier proxy. Rules also determine the prefix that the end user enters into their video endpoint as the dial string.
The number of rules needed depends on how the customer and the carrier want to organize things. If the customer engages one carrier to deliver all the calls they want to make, then only one rule is needed, however, the customer could have more than one rule.
For example, a customer can have a rule for each destination country where calls are made to, or a rule per caller-id. Having one rule per country means they can set the prefix to the International Direct Dial and Country Code so that the end user doesn’t have to enter those details in addition to the prefix when placing a call.
Here are some examples showing different configurations of Prefix and Strip prefix or not, and consequently what the user must enter to place a call, and what the carrier receives. Note that all dial strings end with @example.com (where @example.com represents the domain the customer uses on the Pexip Service) to make a valid SIP address.
